A periscope on a tank works by using mirrors to reflect light from the outside to allow the viewer to see what is happening above the tank, without exposing themselves to potential enemy fire. The periscope is mounted on top of the tank and the viewer can adjust the angle of the mirrors to change the viewing direction.

Which lens is used in periscope?

Periscopes typically use a combination of lenses, including prisms, to help redirect and magnify light entering the periscope. These lenses work together to ensure that the image transmitted through the periscope remains clear and focused for the viewer.


What is role of reflection in periscope?

Reflection plays a crucial role in a periscope by allowing light to bounce off the mirrors inside the periscope, enabling the viewer to see objects that are not in their direct line of sight. The mirrors are positioned at specific angles to reflect the light and create an image for the viewer to see. This process of reflection is what enables a periscope to work effectively in transmitting images from a distant object to the viewer's eye.


Does a periscope work on reflection of light?

Yes, a periscope works by using mirrors to reflect light at an angle to allow a viewer to see around obstacles or over obstacles such as walls, fences, or across distances.


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 does reflection work in a periscope?

In a periscope, light enters through one end and hits a mirror placed at a 45-degree angle. The mirror then reflects the light upwards to another mirror at the top of the periscope, which reflects the light out the other end. This allows a viewer to see objects outside the direct line of sight.
