Rainbow is a phenomenon due to the combined effect of

(A) Interference
(B) Dispersion
(C) Reflection
(D) Refraction
(E) Scattering

Choose the correct answer from the options given below:

(B), (C) and (D) only

The correct answer is Option (2) → (B), (C) and (D) only

Rainbow formation occurs due to the combined effect of:

→ Dispersion — Splitting of white sunlight into different colors inside the raindrop.

→ Refraction — Bending of light when it enters and leaves the raindrop.

→ Reflection — Internal reflection of light within the raindrop that directs it toward the observer.

∴ Correct effects involved: (B), (C), and (D)
