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.

How does the length of the periscope affect the size of the image seen?
The length of the periscope does not affect the size of the image seen. The size of the image is determined by the mirrors inside the periscope that reflect the light, not the length of the periscope itself.
What are the properties of image formed in a periscope?
The image formed in a periscope is virtual, upright, and laterally inverted. It appears closer and magnified compared to the actual object. The periscope uses multiple reflections to achieve this image formation.
How many mirrors are there in a periscope?
A periscope typically contains two mirrors - one at each end of a hollow tube. The first mirror at the top of the periscope reflects the image into the tube, and the second mirror at the bottom of the periscope reflects the image out to the viewer's eye.
Why isn't the image in a periscope laterally inverted?
The image in a periscope is not laterally inverted because it undergoes two reflections inside the periscope, which cancel out the inversion. When light reflects off two mirrors in the periscope, the orientation of the image is maintained.
Do concave lenses always produce a smaller image?
Concave lenses can produce either smaller or larger images, depending on the object's distance from the lens and the characteristics of the lens itself. The image produced by a concave lens can be virtual, upright, and smaller, or it can be real, inverted, and 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 a real image enlarged?
Yes, a real image can be enlarged by using lenses or mirrors to increase its size. The process involves bending the light rays without affecting the quality of the image.
Can the image produced by a convex mirror ever be larger than the image?
No, the image produced by a convex mirror is always virtual and diminished compared to the object. The rays reflect off the mirror divergently, causing the image to appear smaller.
Is an image in a flat mirror smaller larger or the same or the size?
same size
How does a periscope use multiple reflections to view images?
A periscope uses multiple reflections to view images by bouncing light off two or more mirrors inside the periscope. These mirrors are positioned at specific angles to redirect the light path and create an optical pathway that allows the viewer to see objects that would normally be out of direct line of sight. The multiple reflections ensure that the image is correctly oriented and not inverted.
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).
Why isn't the image in a periscope laterally inverted?
The image in a periscope is not laterally inverted because it undergoes two reflections inside the periscope, which cancel out the inversion. When light reflects off two mirrors in the periscope, the orientation of the image is maintained.
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.
How would the eye perceive an image created by a concave mirror and by a convex mirror?
The image formed by a concave mirror can be real or virtual, depending on the object's position relative to the mirror. A real image is formed in front of the mirror and can be projected onto a screen, while a virtual image is formed behind the mirror and cannot be projected. Conversely, a convex mirror always produces a virtual, upright, smaller image of the object. The image appears closer to the mirror than the actual object and does not form a focused point.
