What is periscope ? Describe it's working?​

Answer 1

Answer:

A periscope lets you look around walls, corners or other obstacles.

In a periscope, light from an object strikes the top mirror at 45° and bounces off at the same angle. This sends light directly down the tube and onto the lower mirror. This mirror, also at a 45° angle, reflects light directly to your eye.
