Answer #1

Crtical angle of internal reflection is when light neither refracts nor reflects off a medium. It just grazes along with the surface. Hence, correct option is D.

Critical angle is the angle,at which light neither reflects nor refracts,it just grazes along with the surface.

Snell's Law and the Law of Reflection explain how light is redirected when it encounters a surface between two media. In the extreme, light may only reflect at a boundary, and go back into the medium it was in. More often, some of it reflects and some goes through. If the boundary is plane and flat, then these laws are easy to interpret. When the boundary is curved, they describe happens at every point on the surface. One of the...
