Question

Which of the following explains what happens when light travels from one mediuminto a medium with a lower index of refraction?(A) the speed of light increases(B) the angle of refraction is smaller than the angle of incidence(C) the refracted light bends toward the normal(D) the angle of incidence equals the angle of refraction

Answer 1

Since the speed of light in a medium is inversely proportional to the refractive index, then the speed of light in the medium increases. [Option A]
