The light then bounces down to the bottom mirror. When that reflected light hits the second mirror it is reflected again at 45°, right into your eye.Why do people use periscopes?

Is plane mirror used in Periscope?
Periscope is an optical instrument which uses a system of prisms, lenses, or mirrors to reflect images through a tube. In this instrument, plane mirrors are used to fold light so that the image of an object can be brought down to a lower level.What is Kaleidoscope in science?

This is because the light rays from the object are reflected by two mirrors. The image formed by a plane mirror has four properties: 1. It is upright. periscope Solutions: The image formed will be equal distance perpendicular to the mirror (follows the 5 characteristics of mirror image).How do you mirror on Periscope?
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. This sends light directly down the tube and onto the lower mirror.Which mirror is used in Periscope?
