What is mirage?

A mirage is like when you think you see something that isn’t really there, it’s a trick your eyes play on you.

Imagine you're walking on a hot road in the summer. You might see what looks like water shimmering ahead of you, but when you get closer, it's just the road. That’s a mirage!

How it works

Think about how light travels. Normally, light goes straight, like a train on a track. But when it moves from one material to another (like from air to water), it changes speed and direction, kind of like when you're riding your bike and suddenly hit a patch of wet pavement, you might wobble a bit.

In the case of a mirage, hot air near the road is lighter than cooler air above it. Light rays bend as they move through these layers, making things look different, sometimes even like water! Your brain thinks it’s seeing real water, but it's just a cool trick that happens every day on a sunny day.
