“A rainbow is the combined effect of the refraction, dispersion and total internal reflection of light.” Prove this statement with the help of diagram and explain it.

Answer 1

1. The rainbow is a wonderful phenomenon that combines several phenomena, including internal reflection, refraction and dispersion of light.
2. Following a rainstorm, a rainbow appears in the sky.
3. The droplets of water function as tiny prisms.
4. When water droplets in the atmosphere enter, they refract and disperse incident sunlight, producing a spectrum.
5. The light rays are then internally reflected within the droplet before being refracted.
6. The seven-colored rainbow is seen as a result of all these occurrences together.
7. A rainbow can be observed in the morning on the west and in the evening on the east.
