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.

Is a real image enlarged?
A real image formed by optical devices may be larger or smaller than the object of which it's an image.
Can the image produced by a convex mirror ever be larger than the image?
ONly virtual image is possible in case of convex mirror and the image has to be smaller than the object. So no chance for the image to be larger in any way.
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.
Why isn't the image in a periscope laterally inverted?
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.
How would the eye perceive an image created by a concave mirror and by a convex mirror?
A concave mirror will focus an image and make it appear smaller. A convex mirror will disperse an image and make it appear larger.
Why do you see the image upside down on a periscope?
If the angles of the mirrors that you used on periscope are not parallel to each other you would see the image upside down.

Is an image in a flat mirror smaller larger or the same or the size?
same size

Why is a dilation not an isometry?
Because the image is not the same size as the preimage. To do a dilation all you do is make the image smaller or larger than it was before.
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.
What is a periscop?
A periscope is a device used for seeing a correct image from a hidden place
What are the three types of dilations in math?
The three types of dilations are an enlarged image (the image is larger than the preimage), a reduced image (the image is smaller than the preimage) and an equal image (the image is the same size as the preimage).

What is the number used to multiply the lengths of a figure to make a larger or smaller similar image?
That's referred to as the scale.
