Question

Rainbow is formed due to a combination of (a) Dispersion and total internal reflection (b) Refraction and absorption (c) Dispersion and focussing (d) Refraction and scattering

Answer 1

Answer:

(a)

Explanation:

dispersion and TIR

Answer 2

Option A is the right answer. A rainbow is formed due to a combination of Dispersion and total internal reflection.

• Due to the striking of sunlight on the water droplets, a multi-colored arc is formed in the sky.
• The arc contains 7 colors in the order VIBGYOR.
• This arc is called rainbow.
• When sunlight falls on a drop of water, it gets split into seven colors forming a spectrum this is called dispersion.

• If the angle of incidence is greater than the critical angle, the light rays undergo total internal reflection.
• These are the two phenomena responsible for the rainbow.
