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.
What else can I help you with?
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 is concave lens in a periscope?
A concave lens in a periscope is used to invert the image received from the object being observed. This type of lens helps to create a larger field of view within the periscope by expanding the image. The concave lens also helps to focus the incoming light rays onto the mirror system of the periscope for reflection.
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?
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 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.

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.
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.
Is an image in a flat mirror smaller larger or the same or the size?
same size
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 the image in the periscope is upright?
The periscope uses a system of mirrors to reflect and redirect light, allowing the observer to see around obstacles such as the walls of a trench or the side of a ship. The mirrors in the periscope are strategically angled in a way that maintains the orientation of the image, resulting in an upright view for the observer.
Is a periscope a concave lens?
No, a periscope uses mirrors to reflect light and change the direction of the image, not a concave lens which diverges light rays.
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.
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.
