Question

An incident ray traveling in a slower medium strikes a boundary with a faster medium. What happens when its angle of incidence is greater than the critical angle? A. The refracted ray makes an angle of 90°. B. There is total internal reflection in the faster medium. C. There is total internal reflection in the slower medium. D. The reflected ray makes an angle of 90°. E. The reflected ray makes an angle equal to the critical angle.

Answer 1

there will be a total internal reflection in the slower medium and the reflected ray will make an angle equal to incident angle (not critical angle) which is larger than critical angle. All the laws of reflection are satisfied and there is almost 100 % reflection.
