I have noticed that sometimes on a hot day, while travelling, I will see a water puddle on the road a little far away but when the car reaches there, there is no puddle or water.
I tried searching about this but couldn’t really understand why light changes its direction and we perceive it as a virtual image which looks like water.
I would really like to understand why this really happens.
Thanks!

Light bends as it travels through air. Air’s temperature determines how much light bends. Usually light bends from hotter areas toward colder areas.
Distant light which would have terminated at a particular spot on the hot ground instead bends up in the warm air and heads toward your eyes.
