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.

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.
Why the image of a periscope is upright?
The periscope uses a system of angled mirrors to reflect light coming in from above the water surface at an angle of 45 degrees downwards, and then reflects it again to the viewer's eye at a 45 degree angle upwards. This system of reflection allows the viewer to see an upright image despite the periscope being underwater and the image being inverted initially.
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?
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.

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.
Will the image be smaller or larger in a periscope?
The image will be larger in a periscope due to the reflections of light within the tube. The light traveling through the periscope bounces off several mirrors, which results in magnification of the image as it reaches the viewer's eye.
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.
Is image in a plane mirror upright?
Yes, the image in a plane mirror appears upright and the same size as the object.
Why does the fact that a periscope has two mirrors make what you see through it easier to understand?
The two mirrors in a periscope work together to reflect and invert the image twice, allowing the viewer to see the image in the correct orientation. This design helps to compensate for the natural inversion caused by reflection and ensures that the image appears upright and aligned with what the viewer would see with the naked eye.
