Hi everyone,
Is the following explanation correct?
On a sunny day the surface of the road and the air just above it get very hot. The air just above that is fairly cool in comparison. Now, light travels faster through warm air than it does through cold air because warm air is less dense. Hence, when light hits that hot air just above the road surface at a certain angle, it changes speed and is bent upward. As a result, the light that hits your eye shows you a patch of sky where the road should be, an inferior mirage
