What are the principals of periscope? What are its uses?
Answers
Answer:
The principle of working of periscope is based on Reflection and Refraction. Periscope, consisting of two mirrors at 45 degrees, helps to see things above water from inside the depth of the water. It is usually used by the submarines.
Answer:
A periscope is based on the Laws of Reflection, which says that the light from the object falls on a mirror at an angle of 45 degrees from the surface and is mirrored. The mirrored light then falls on another mirror and is mirrored again until it enters the human eye.
