A. dispersion
B. refraction
c. total internal refraction
D. refraction
What is the correct order in which the following processes occur when a rainbow is formed after a rain shower?
A. dispersion
B. refraction
c. total internal refraction
D. refraction
- BACD
- ABCD
- DCBA
- BCDA
Hint:
First refraction occurs in order to form a rainbow. The white light enters the water droplets.
The correct answer is: BACD
Refraction causes light to travel in a bend path inside the water droplets, whereas dispersion scatters the different colored light to form a rainbow followed by dispersion , then total internal refraction and at last refraction takes place splitting all the colors of the white light resulting in forming a rainbow.
Hence, the correct option is a)BACD.
Hence, the correct option is a)BACD.
