When light from air hits a smooth piece of glass with the ray perpendicular to the glass surface,the part of the light passing into the glass:
A)will not change its speed.
B)will not change its frequency.
C)will not change its wavelength.
D)will not change its intensity.

Question

Quizplus · Accepted Answer

When light transitions from one medium to another, its speed and wavelength can change due to the difference in the refractive index of the two media. However, the frequency of the light remains constant because it is determined by the source of the light and does not change when light moves from one medium to another.
