Question

The formation of a rainbow in the sky involves:

• A. reflection, refraction, scattering
• B. refraction, dispersion, reflection
• C. refraction, scattering, dispersion
• D. dispersion, total internal reflection, scattering

Hint:

Rainbow formation involves: - Bending of light (refraction) - Splitting of light into colors (dispersion) - Bouncing of light (reflection)

Answer 1

The Correct Option is B

Step 1: Recall the phenomena involved in rainbow formation.
Rainbows are formed by the interaction of sunlight with water droplets. 
Step 2: Describe the sequence of events.
1. Sunlight enters a raindrop and undergoes refraction, which also causes the white light to split into its constituent colors (dispersion).
2. These different colors of light then undergo internal reflection from the back surface of the raindrop.
3. Finally, the light undergoes another refraction as it exits the raindrop, further separating the colors and directing them towards the observer's eye.
Step 3: Identify the correct sequence from the options.
The correct sequence of phenomena involved in rainbow formation is refraction, dispersion, and reflection.
