A periscope uses energy to function by using mechanical energy to raise and lower the viewing device, and by using optical energy to transmit and reflect light to enable viewing in a different direction than the physical position of the viewer. Electric energy may also be used to power any motorized components in the periscope.

How does the periscope use the properties of light?
A periscope uses the property of reflection to redirect light. Light enters through one end of the periscope, reflects off multiple mirrors inside the periscope, and exits out the other end, allowing the viewer to see an object that is not in their direct line of sight.
Did periscope use convex or concave mirror?
The basic periscope uses flat mirrors, to bend and offset the optical path. If magnification is required, then the periscope will use convex objective and eyepiece lenses, becoming a refracting telescope with an offset in its optical path.
Explain how can you see periscope to look over a wall?
To use a periscope to look over a wall, you would place the periscope on top of the wall and then look into the eyepiece at the other end. The mirrors inside the periscope will reflect the view from above the wall down to your eye, allowing you to see over the wall without exposing yourself.

Periscopes typically use a combination of lenses, including prisms, to help redirect and magnify light entering the periscope. These lenses work together to ensure that the image transmitted through the periscope remains clear and focused for the viewer.
How does a periscope use reflection?
A periscope uses reflection by directing light at an angle through two mirrors to view objects that are not in direct line of sight. The first mirror at the top of the periscope reflects light down, while the second mirror reflects it out to the observer, allowing them to see objects above the periscope's position.

What property of light does a periscope make use of?
A periscope makes use of the property of reflection to redirect light. Light enters one end of the periscope, reflects off mirrors inside the periscope, and then exits at the other end, allowing the viewer to see objects outside their direct line of sight.
How the use of mirrors helps the user of a periscope see above the water surface?
The mirrors are fitted at 45 degree angles in a periscope in the opposite directions. when you see through the periscope, the image gets reflected.
