Answer:
Concave mirror

Question 3.
If an object is placed at the focus of a concave mirror, where is the image formed?
Answer:
Infinity.

Question 4.
Why does a ray of light bend when it travels from one medium to another?
Answer:
The bending of light rays when they pass obliquely from one medium to another medium is called refraction of light.

Light rays get deviated from their original path while entering from one transparent medium to another medium of different optical density. This deviation (change in direction) in the path of light is due to the change in velocity of light in the different mediums. The velocity of light depends on the nature of the medium in which it travels.

Question 5.
What is speed of light in vacuum?
Answer:
The only medium in which speed of light is equal to that in a vacuum is air. Speed of light in a vacuum is 3 × 10⁸ m/s. Armand Fizeau first measured the speed of light.

Question 6.
Concave mirrors are used by dentists to examine teeth. Why?
Answer:
As a dentist’s head mirror: You would have seen a circular mirror attached to a band tied to the forehead of the dentist/ENT specialist. A parallel beam of light is made to fall on the concave mirror; this mirror focuses the light beam on a small area of the body (such as teeth, throat etc.).

VII. Answer briefly.

Answer:
Rear-view mirror, Dentist’s mirror, Torch-light mirror, Mirrors in shopping malls, Make-up mirror.

Concave mirror	Convex mirror
Dentist’s mirror	Rear view mirror
Torch light mirror	Mirrors in shopping malls
Make-up mirror

Question 3.
State the direction of the incident ray which after reflection from a spherical mirror retraces its path. Give reason for your answer.
Answer:
The incident ray is directed towards the centre of curvature
Reason: The ray is normal to the spherical mirror, so ∠ i = o, .’. ∠r = o

Question 4.
What is meant by magnification? Write its expression. What is its sign for real image and virtual image?
Answer:
Magnification produced by a spherical mirror gives how many times the image of an object is magnified with respect to the object size.
It can be defined as the ratio of the height of the image (h_i) to the height of the object (h_o).
Magnification = m = \(\frac{h_{i}}{h_{o}}=\frac{\text { height of the image }}{\text { height of the object }}\)

• for real image it is negative,
• for virtual image it is positive.

Question 5.
Write the spherical mirror formula and explain the meaning of each symbol used in it.
Answer:
Mirror formula:
\(\frac{1}{f}=\frac{1}{u}+\frac{1}{v}\)
Here, f – focal length of a spherical mirror
u – distance of the object from the pole of the mirror
v – distance of image from the pole of the mirror

VIII. Answer in detail.

Question 1.

1.  at C
2.  between C and F
3.  between F and P of the mirror.

Answer:
(1) At the centre of curvature C

(2) Between C and F

(3) Between the focus F and the Pole P of the mirror.

(b) Mention the position and nature of image in each case.
Answer:

Position of object	Position of Image	Nature of Image
At the centre of curvature C	AtC	Real and Inverted
Between C and F	Beyond C	Real and inverted
Between F and P	Behind the mirror	Virtual and Erect

Question 2.
Explain with diagrams how refraction of incident light takes place from
(a) rarer to denser medium
(b) denser to rarer medium
(c) normal to the surface separating the two media.
Answer:
(a) rarer to denser medium:
When a ray of light travels from an optically rarer medium to an optically denser medium, it bends towards the normal.

(b) denser to rarer medium:
When a ray of light travels from an optically denser medium to an optically rarer medium it bends away from the normal.

(c) normal to the surface separating the two media:
A ray of light incident normally on a denser medium goes without any deviation.

IX. Numerical Problems.

Question 1.
A concave mirror produces three times magnified real image of an object placed at 7 cm in front of it. Where is the image located? (21 cm in front of the mirror)
Answer:
Given: h_i = 3h_o
u = 7 cm
Solution:

1. m = \(\frac{h_{i}}{h_{O}} \Rightarrow \frac{3 h o}{h_{O}}\) ∴ m = 3.
2. m = – \(\frac{v}{u}\)
   v = – m × u
   = – 3 × 7 cm = – 21 cm.
   Hence, a real, inverted, and the magnified image will be formed at 21 cm in front of the mirror.

Question 2.
Light enters from air into a glass plate having a refractive index 1.5. What is the speed of light in glass? (2 × 10⁸ ms^{– 1})
Given: Refractive index (µ) = 1.5
Speed of light in vacuum (c) = 2 × 10⁸ms^{– 1}
Speed of light in glass (υ) = ?
Solution:

∴ Speed of light in glass = 1.3 × 10⁸ ms< sup>- 1

Question 3.
The speed of light in water is 2.25 × 10⁸ms^{– 1}. If the speed of light in vacuum is 3 × 10⁸ms^{– 1}, calculate the refractive index of water.
Given:
Speed of light in water (υ) = 2.25 × 10⁸ms^{– 1}
Speed of light in vacuum (c) = 3 × 10⁸ms^{– 1}
Solution:
μ = \(\frac{c}{υ}\) ⇒ μ = \(\frac{3 \times 10^{8} \mathrm{ms}^{-1}}{2.25 \times 10^{8} \mathrm{ms}^{-1}}\)
∴ μ = 1.33

X. HOTS.

Question 1.
Light ray emerges from water into air. Draw a ray diagram indicating the change in its path in water.
Answer:

When a ray of light travels from dense medium to rarer medium [from water medium to air medium], light ray moves away from the normal.
∴ Angle of incidence < Angle of refraction.

Question 2.
When a ray of light passes from air into glass, is the angle of refraction greater than or less than the angle of incidence?
Answer:

When a ray of light travels from rare (air) medium to dense [glass] medium, light ray moves towards the normal.
∴ Angle of refraction < Angle of incidence.

Question 3.
What do you conclude about the speed of light in diamond if the refractive index of diamond is 2.41? way from the mirror. Does the image become smaller or larger? What do you observe?
Answer:
µ = 2.41; Ca = 3 × 10⁸ms [Velocity of light]
µ = \(\frac{\text { Speed of light in air }}{\text { Speed of light in diamond }}=\frac{\mathrm{C}_{\mathrm{a}}}{\mathrm{C}_{\mathrm{d}}}\)
C_d = \(\frac{C_{a}}{\mu}=\frac{3 \times 10^{8}}{2.41}\) = 1. 245 × 10⁸ m/s
∴ Speed of light decreases when the light ray travels from air to diamond.

ACTIVITY

Question 1.
Stand before the mirror in your dressing table or the mirror fixed in a steel almirah. Do you see your whole body?
Answer:
To see your entire body in a mirror, the mirror should be atleast half of your height.
Height of the mirror = Your height/2.

Question 2.
Hold a concave mirror in your hand (or place it in a stand). Direct its reflecting surface towards the sun. Direct the light reflected by the mirror onto a sheet of paper held not very far from the mirror. Move the sheet of paper back and forth gradually until you find a bright, sharp spot of light on the paper. Position the mirror and the paper at the same location for few moments. What do you observe? Why does the paper catches fire?
Answer:
The concave mirror focus the sunlight at one particular point. At that particular point, amount of sunlight is converged and heat is trapped at that point. This is because, it bum the paper on which the image is focused.

Question 3.
Take a convex mirror. Hold it in one hand. Hold a pencil close to the mirror in the upright position in the other hand. Observe the image of the pencil in the mirror. Is the image erect or inverted? Is it diminished or enlarged? Move the pencil slowly away from the mirror. Does the image become smaller or larger? What do you observe?
Answer:
When we hold a pencil in the upright position in front of a convex mirror we observe the image of the pencil at the back of the mirror. The image is erect, virtual and smaller in size than the object. As the pencil is moved away from the mirror, the image becomes smaller. When the object is moved away from the mirror, the image would move closer to the focus of the mirror.

Question 4.
Refraction of light at air – water interface
Put a straight pencil into a tank of water or beaker of water at an angle c 45° and look at it from one side and above. How does the pencil look now?
Answer:

The pencil appears to be bent at the surface of water.

Samacheer Kalvi 9th Science Light In Text Problems

Question 1.
Find the size, nature and position of the image formed when an object of size 1 cm is placed at a distance of 15 cm from a concave mirror of focal length 10 cm.
Solution:
Object distance, u = – 15 cm (to the left of mirror)
Image distance, v = ?
Focal length,f = – 10 cm (concave mirror)
Using mirror formula,

Thus, image distance, v = – 30 cm (negative sign indicates that the image is on the left side of the mirror).
∴ Position of image is 30 cm in front of the mirror. Since the image is in front of the mirror, it is real and inverted.
To find the size of the image, we have to calculate the magnification.
m = \(\frac{-v}{u}=\frac{-(-30)}{(-15)}\) = – 2
We know that, m = \(\frac{h_{2}}{h_{1}}\)
Here, height of the object h₁ = 1 cm
– 2 = \(\frac{h_{2}}{1}p.\)
h₂ = – 2 × 1 = – 2 cm
The height of image is 2 cm (negative sign shows that the image is formed below the principal axis).

Question 2.
An object 2 cm high is placed at a distance of 16 cm from a concave mirror which produces a real image 3 cm high. Find the position of the image.
Solution:
Height of object h₁ = 2 cm
Height of real image h₂ = – 3 cm

The position of image is 24 cm in front of the mirror (negative sign indicates that the image is on the left side of the mirror).

Question 3.
A car is fitted with a convex mirror of focal length 20 cm. Another car is 6 m away from the first car. Find the position of the second car as seen in the mirror of the first. What is the size of the image if the second car is 2 m broad and 1.6 m high?
Solution:
Focal length = 20 cm (convex mirror)
Object distance = – 6m = – 600 cm
Image distance v =?

Height of image = \(\frac{1}{31}\) × 160 cm = 5.16 cm

Question 4.
The speed of light in air is 3 × 10⁸ ms^{– 1} and in glass it is 2 × 10⁸ ms^{– 1}. What is the
refractive index of glass?
Solution:
\(_{a} \mu_{g}=\frac{3 \times 10^{8}}{2 \times 10^{8}}=\frac{3}{2}\) = 1.5

Question 5.
Light travels from a rarer medium to a denser medium. The angles of incidence and refraction are respectively 45° and 30°. Calculate the refractive index of the second medium with respect to the first medium.
Solution:
Angle of incidence i = 45° ; Angle of refraction r = 30°
\(_{1} \mu_{2}=\frac{\sin i}{\sin r}=\frac{\sin 45^{\circ}}{\sin 30^{\circ}}=\frac{1 / \sqrt{2}}{1 / 2}=\sqrt{2}\) = 1.414
