The principle of periscope is based on the laws of reflection
As u know that inside the periscope the mirror s are placed at an angle of 45 degrees from each other .the light comind from the object is reflected by the mirror at an angle of 45 degrees the the reflected light again gets reflected this happens until the light reaches the eye of the observer
I hope this helps
