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.
What image will be formed in magnifying glass?
The image is magnified,virtual and upright
What is an upright image?
The image produced by the lens is above the principle axis.
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.
Will the image be smaller or larger in a periscope?
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 is upright image?
Meaning of upright image
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.

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 is an upright image?
The image produced by the lens is above the principle axis.
What image will be formed in magnifying glass?
The image is magnified,virtual and upright
What type of image does a plain mirror produce?
real and upright image

Which lens always produces an image that is upright?
Concave lens (diverging) produces an upright image that is virtual. Although to create a real upright image would require 2 convex (converging) lens with a distance of their respective focal lengths between them.

What image do you see of yourself in a plane mirror?
the image upright, virtual and the same size as you..
