FAQs on Summary Video: Light Reflection and Refraction

Question 1

1. What is the difference between light reflection and refraction?

Accepted Answer

Ans. Light reflection is the bouncing back of light rays from a surface, whereas light refraction is the bending of light rays as they pass from one medium to another.

Question 2

2. How does a mirror produce an image through reflection?

Accepted Answer

Ans. A mirror produces an image through reflection by reflecting light rays that strike its surface, creating a virtual image that appears to be behind the mirror.

Question 3

3. How does the refractive index affect the amount of bending of light during refraction?

Accepted Answer

Ans. The refractive index of a material determines how much light will bend when passing through it. A higher refractive index means more bending of light.

Question 4

4. Can light change speed when it travels from one medium to another during refraction?

Accepted Answer

Ans. Yes, light can change speed when it travels from one medium to another during refraction, leading to the bending of light rays.

Question 5

5. Why does a pencil appear bent when partially submerged in water?

Accepted Answer

Ans. A pencil appears bent when partially submerged in water due to the bending of light rays as they pass from air to water, creating an optical illusion of the pencil being bent.
