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.
The basic periscope simply shifts the line of sight, so that you can see around a corner or over a wall. It doesn't necessarily do anything to the image just because it's a periscope. But there's no reason you can't add a telescope or wide-angle viewer to a periscope, or even a zoomer to take you smoothly from a wide-angle to a telephoto, in order to add those functions to the shifted line of sight.
The image formed by the convex mirror is virtual, erect and diminished.

If the angles of the mirrors that you used on periscope are not parallel to each other you would see the image upside down.
The submarine's periscope and radar mast are damaged.

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.
A periscope is a device used for seeing a correct image from a hidden place

The image formed by a plane mirror is virtual image.
Yea if you really want to know more about the periscope than go to a website with more knowledge and try to do more research
image formed by the concave lens will be erect , virtual and smaller than the size of object.
The inverted or upside-down image is formed on the retina.
