A simple periscope can be made of basically two mirrors and a pipe.
The 1st mirror is set at 45 degrees and inverts the image. The 2nd is set below and inverts the image again so you get a proper image.

It's used for seeing around where you can't usually see (like a submarine seeing above water).
More complex periscopes are made of many lenses and prisms, or advanced fiber optics, which can give you many more options. There is also an eyepiece, a wheel for rotating the tube, gearing, and depending on the type of periscope, an objective, which would be where you see out... which could be set with a lens, a camera, just be a simple part of the tube, or something much more complex depending on how the periscope is made.
The periscope has several parts: the ocular lenses, the mirror or prism, inversion/reversion prisms, relay lenses, another mirror or prism, and objective lenses.
Basically to see around corners, do it twice and you have the device that's common on submarines.
Yes, "periscope" is a compound word. It is formed from two Greek roots: "peri," meaning "around," and "skopein," meaning "to look." Together, they convey the idea of looking around, which is the function of a periscope, typically used in submarines or for viewing over obstacles.

someone discovered the periscope
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.
well there really is no antonym that i know of for periscope because a periscope is an object.
