Question

Quizplus · Accepted Answer

When monochromatic light passes from air to glass and back to air, both the wavelength and speed of the light change. The wavelength of the light decreases when it enters the denser medium of glass, and then increases when it exits back into air. Additionally, the speed of light is slower in glass than in air, so the speed changes as well.
