Question

does rainbow forms always opposite to sun why ....

Answer 1

yes rainbow forms opposite to Sun becoz the sunlight disperses through the water drops in opposite directions

Answer 2

Answer:

The sun is always in the opposite part of the sky from the center of the rainbow. This is because a rainbow is actually just sunlight which has been refracted and reflected. Refraction occurs when the sunlight enters and leaves the small spherical water droplets that constitute the mist.
