Question

The rainbow formation could be because of the following reasons
A. light being reflected when entering a droplet of water, then refracted inside on the back of the droplet and refracted again when leaving it.
B. light being refracted and dispersed when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.
C. Due to interference of different wavelengths in white light
D. All scenarios possible.​

Answer 1

Answer:

c. due to interference of diff.wavelength in white light

Answer 2

The rainbow formation could be because of the B. light being refracted and dispersed when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.

• Rainbows are created when sunlight is scattered by water droplets in a process of refraction.
• When sunlight passes through a medium denser than air, such as a raindrop, it refracts, changing its direction.
• When light enters the raindrop, it is refracted, reflected off the back, and then refracted again as it escapes and travels to our eyes.
• The internal reflection only occurs if the angle of incidence is greater than the critical angle.
