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 distance the light has traveled from its source.
C)the temperature of the refracting medium.
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 from one medium to another is determined by the total change in its velocity. This means that the refractive index of the two media, which is related to the speed of light in each medium, determines the degree of bending. The greater the change in velocity, the greater the bending of light. None of the other factors listed have a significant effect on the degree of bending of light.
