Question

Give reason for the formation of Mirage

Answer 1

Its formation is a result of the refraction and the total internal reflection of light in the air. To investigate the formation of a mirage, we firstly need to understand why light is refracted in the air. ... The closer the air is to the ground, the hotter it will be, and its refractive index will be smaller.

Answer 2

Mirges happens when the ground is very hot and air is cool. The hot ground warms a layer of air just above the ground when the light moves through the cold air & into the layer of hot air it is refracted
