What causes the phenomenon of a mirage in deserts or on roads?

A mirage happens when hot air makes things look like they're not really there, just like when you see a puddle on a hot road that isn’t really there.

Hot air is lighter than cold air, so it moves up and around. When the sun beats down on the road, it warms up the air near the ground. This warm air rises in wiggly paths, bending the light that comes from far away, like a car or a tree.

Imagine you're looking at a shiny bicycle across the street. The light from the bike travels straight to your eyes most of the time. But when it hits hot air near the road, the light bends, kind of like how light bends in a water glass or through a prism.

This bending makes things look wobbly or even appear as if they're floating above the ground. That’s why you might see what looks like water on a hot, dry road, it's not really there; it's just light playing tricks on your eyes!

It’s like looking at a pencil in a glass of water and seeing it bend, the same idea is happening with mirages. The only difference is that instead of a pencil, you're seeing something far away, and instead of water, you’re seeing hot air playing tricks!
