The top of the periscope has a prism that reflects the light to the observers prism. The object the top prism is pointed at is seen at the bottom one.
You can look over a wall with a periscope because the tube has mirrors what are on a 45 degree angle so the light goes in the top, reflects off the top mirror, then onto the bottom mirror and then into your eyes. Don't forget: Light only travels in straight lines
A periscope is an optical instrument that uses a system of prisms, lenses, or mirrors to reflect images through a tube. Light from a distant object strikes the top mirror and is then reflected at an angle of 90 degrees down the periscope tube. At the bottom of the periscope, the light strikes another mirror and is then reflected into the viewer's eye.
This is kind of hard to describe without the use of a diagram, but I'll do my best: A periscope lets light (or the image) in through the lense which, much like the lense in a human eye actually inverts the image. It is then reflected onto a mirror which angles it down the shaft of the periscope. At the bottom, there is another mirror which reflects the image into the eye piece and corrects the orientation of the image.
Because there are two mirrors: one at the bottom and one at the top. If there was only one mirror in it, it would be, but because the image is inverted in one mirror, then that image is inverted again in the second mirror, it goes back to normal and you see the normal image which is entering the periscope at the other end.

it reflects
With mirrors. A simple periscope can be constructed out of a vertical tube with mirrors placed at a 45-degree angle at the top and bottom of the tube.
It depends on the submarine. If measure the distance from the top a fully extended periscope to the bottom of the boat you will get the "Depth of the Keel" at which the periscope is out of the water. Generally between 30 feet and 70 feet.

Tape a mirror to the inside of each flap. cut away the side of the cardboard opposite each flap. Angle both mirror flaps inward about 30 degrees. Look through the bottom of the periscope to see that what is seen on the top mirror is also reflected on the bottom mirror.

Down periscope!
Simply a periscope is a tube with two right angles top and bottom. In the right angle section two mirrors are set at a 45 degree angle. Thus light coming in the top horizontal tube hits the mirror and is reflected down the vertical bit of the tube where it hits the second mirror and is reflected out horizontally again.
It's usually used in reference to gay relationships and reflects who is dominant and who is passive. A "top" is the dominant member, and the "bottom" is the passive. It may also refer to who takes which position in a sexual encounter.
