When light is refracted, the degree of bending is determined in part by:
A) the total change in velocity as the light passes from one medium to the next.
B) the temperature of the refracting medium.
C) the distance the light has traveled from its source.
D) the length of time the light takes to travel through the refracting medium.

Question

Quizplus · Accepted Answer

The degree of bending of light when it passes through a refracting medium depends on the total change in velocity that the light experiences as it moves from one medium to another. This change in velocity causes the light to bend towards the normal line, which is an imaginary line perpendicular to the surface of the refracting medium. The greater the change in velocity, the greater the degree of bending. The other options (B, C, D) do not affect the degree of bending of light when it passes through a refracting medium.
