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.

Answer 2

Answer:

This occurs when a ray of light passes from a optically denser medium to a less denser medium in this the speed of light at first is slow because it is passing from dense object and at last the speed becomes fast because it is passing from a less denser medium
