Question

3 working principle of flat mirrors in a periscope

Answer 1

$\huge\mathbb{\underline{Answer:-}}$

A periscope works on the Laws of Reflection which states that the light from the object falls on one mirror at a 45o angle from the object and is reflected. This reflected light then falls on another mirror and is again reflected until it reaches the human eye.

The periscope makes use of two plane mirrors to see over the top of things. A periscope works on the reflection of light from two plane mirrors arranged parallel to one another.

A periscope works by using two mirrors to bounce light from one place to another. A typical periscope uses two mirrors at 45 degree angles to the direction one desires to see. The light bounces from one to the other and then out to the persons eye.
