Question

Match the statements of Column A with those of Column B.

Column A (A) Optical fiber communication	Column B (a) Reflection
(B) Apparent depth of swimming pool	(b) Scattering
(C) Formation of image by plane mirror	(c) Total internal reflection
(D) Orange color of the sky	(d) Refraction

• A. A⇢ c , B⇢ a, C⇢ d, D⇢ b
• B. A ⇢b B ⇢c C ⇢d D⇢ a
• C. A ⇢c B⇢ d C⇢ a D⇢ b
• D. A⇢ b B⇢ d C⇢ c D⇢ a

Answer 1

The correct option is C

A ⇢c B⇢ d C⇢ a D⇢ b

Explanation

1. Reflection : When the light hits a smooth surface it bounces back and forms an image. This bouncing back of light and forming image by plane mirror is because of reflection.
2. Scattering : Spreading of light into different directions is called as scattering of light. The color of the sky appears orange because of scattering of light.
3. Total internal reflection : The phenomenon of complete reflection of light within the medium after hitting the surface of the rarer medium. Optical fiber communication is based on this phenomena.
4. Refraction : Bending of light when entering from one medium to another. Apparent depth of the swimming pool is one such example.

Column A (A) Optical fiber communication	Column B (c) Total internal reflection
(B) Apparent depth of swimming pool	(d) Refraction
(C) Formation of image by plane mirror	(a) Reflection
(D) Orange color of the sky	(b) Scattering

Hence, option (C) A ⇢c B⇢ d C⇢ a D⇢ b is the correct answer.
