CoachA periscope uses a system of mirrors to reflect and refract light in order to allow an observer to see objects that are not in direct line of sight. Light enters one end of the periscope, gets reflected by mirrors inside, and then refracted at the eyepiece to reach the observer's eye, providing a view of objects at a different height or distance.

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.
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.
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.
How does the periscope use the properties of light?
A periscope uses the property of reflection to redirect light. Light enters through one end of the periscope, reflects off multiple mirrors inside the periscope, and exits out the other end, allowing the viewer to see an object that is not in their direct line of sight.
Can opaque substances refract light?
No, opaque substances do not refract light. Refraction occurs when light passes through a transparent medium and changes speed, causing the light to bend. Opaque substances do not allow light to pass through them, so there is no refraction.
