Question

principle of kaleidoscope and periscope ​

Answer 1

Answer:

Principle of kaleidoscope

Kaleidoscopes work on the principle of multiple reflections.

The mirrors reflect the images of objects inside, creating a symmetrical pattern. When you look at your reflection in one mirror, you see light that has come from your face and bounced off the mirror.

Principle of periscope

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.

Answer 2

Principle Of Kaleidoscope :-

The basic principles used in the kaleidoscope are the law of reflection, and white light is a combination of VIBGYOR. When the white light hits the surface of the mirror, it gets reflected at an angle such that the angle of incidence is equal to the angle of reflection.

Principle of periscope :-

Periscopes can be constructed using a pair of flat mirrors or prisms and a rectangular hollow tube that has a viewing window at the top and bottom of the tube. The mirrors within this structure are fixed at an angle of 45 degrees at the two ends. More complex periscopes using prisms or advanced fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science
