A periscope can be raised and lowered depending on the depth of a submarine. Periscopes are like a small telescope that can be rotated to take in a 360 degree view of the submarine's surroundings. Periscopes have to be lowered before the submarine is submerged. Periscopes in nuclear submarines are now able to take pictures of surroundings.

What is a periscope in detail?
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.
How are images formed in a mirror?
images are formed in a mirror by putting something up to it.
How does a periscope use multiple reflections to view images?
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.
Would a mirror periscope be better than a prism periscope?
No

What does the prism in the periscope do compared to the mirror usually used?
Mirrors have distortion in the images they project while prisms create undistorted images. :D

What are the properties of images seen in a concave mirror if the object is farther from than the focal point?
The image formed is real, inverted, diminished and on the same side of the mirror as the object is.
