In a periscope, light enters through the top mirror and reflects off the second mirror at the bottom, which then bounces the light out towards the viewer's eye. This allows the viewer to see an image that appears to be coming from the original direction of the light source, creating the illusion of an image appearing straight ahead even though the viewer is looking at it from an angle.

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 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.
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.
Why is the image form using plane mirror in periscope unclear?
The image in a periscope using a plane mirror may appear unclear because plane mirrors do not correct for the inversion of the image (upside-down). This can lead to a distorted or confusing view as the light rays are simply reflected without any modification. More sophisticated periscopes use prisms to correct for the inversion, resulting in a clearer image.

Why do you see the image upside down on a periscope?
In a periscope, light reflects off a series of mirrors at specific angles. This reflection process causes the image to appear upside down when viewed through the periscope.

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 type of image is formed by a lens if m -4.6?
A virtual and upright image is formed if the magnification is negative (-4.6) when using a lens.
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.
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.
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.
