How Periscope Works?

Periscope is like a fun tunnel that lets you see things from far away or around corners.

Imagine you're playing hide and seek in a big hallway. You can’t see your friend because they’re hiding behind a wall. But if you have a long, narrow tube, kind of like a periscope, you can look through it and see your friend even though they're out of your line of sight.

When light from your friend hits the top of the periscope, it goes into the tunnel. The light bounces off two mirrors, which are like super reflective pieces of glass. One mirror sends the light down the tunnel, and the other sends it back up so you can see your friend clearly, just like looking through a tunnel made of mirrors!

The mirrors inside the periscope help the light change direction, kind of like how a ball bounces off a wall when you play catch. This lets you see around corners or over tall objects without moving your head.

So next time you use a periscope, or even peek through a tunnel, remember: it’s all about light and mirrors working together!
