ii) Name the devices in which total internal
reflection of light is used.​

Answer 1

Answer:

Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle.

The phenomenon of total internal reflection of light is used in many optical instruments like telescopes, microscopes, binoculars, spectroscopes, periscopes

Answer 2

Answer:

When the Rays of light bounce of the surface at angle greater than the critical angle and thus stay in the same medium is know as total internal reflection of light.

Devices: camera , binoculars , etc.
