Question

What properties of light are used in a periscope?

Answer 1

- light travels in straight line

- light gets reflected, refracted and absorbed

Answer 2

Answer:A periscope is a useful example of the law of reflection at work. It's important that your mirrors are placed at a 45° angle, because light always reflects away from a mirror at the same angle that it hits it. In a periscope, light from an object strikes the top mirror at 45° and bounces off at the same angle.
