Answer 2

Answer:

There are a total of 2 mirrors in a Periscope.

Explanation:

A simple periscope is just a long tube with a mirror at each end. The mirrors are fitted into each end of the tube at an angle of exactly 45 degrees (45°) so that they face each other. In the periscope, light hits the top mirror at 45° and reflects away at the same angle.
