Question

what is angle of refraction when the light rays under goes totally internally reflected??????​

Answer 1

Answer:

Total internal reflection. As we increase the angle of incidence, we reach a point where the angle of refraction is 90° and the refracted raytravels along the boundary of the two media.

Answer 2

Answer:

When a light

travelling in a denser medium is incident at the surface of a rarer medium at the angle of incidence greater than the critical angle for the pair of media, the Ray is totally reflected back into the denser medium. this phenomenon is called total internal reflection.

The angle of refraction when the light rays are totally internally reflected is:

When a right angle triangle is 30,90,60 degree then total internal reflection occurs...

That means 90 degree is must...
