Answer 1

The principle of working of periscope is based on Reflection and Refraction.

Periscope, consisting of two mirrors at 45 degrees, helps to see things above water from inside the depth of the water.

It is usually used by the submarines.

Periscope works on the principle of reflection because when light hits the surface of the periscope, it does not pass, thus bounces back.
