Question

In rainbow formation total interanl reflection takes place or internal reflection?

Answer 1

Answer:

Explanation:

In nature, rainbows are formed when light from the sun is refracted and undergoes total internal reflection inside rain droplets.. The formation of a rainbow involves a series of physical phenomena -- reflection, refraction, dispersion, and total internal reflection.

Answer 2

Answer: Just "internal reflection," not "total internal reflection."

Explanation: At night, look through a window from a bright room. You will see a reflection, If you look to the side, or the window is thick, you will see two. The point is that some light always reflects off of each side of the window. But total internal reflection cannot happen, because the critical angle cannot be exceeded in a spherical raindrop.
