Define total internal reflection of light. Name the devices in which total internal reflection of light is used.
Answers
Answer:
When the Rays of lightbounce 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.
hope this help you.

Answer:
Explanation:
Total internal reflection is the phenomenon which occurs when a propagated wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface. If the refractive index is lower on the other side of the boundary and the incident angle is greater than the critical angle, the wave cannot pass through and is entirely reflected
The phenomenon of total internal reflection of light is used in many optical instruments like telescopes, microscopes, binoculars, spectroscopes, periscopes etc.
