Monochromatic light hits a piece of glass. Assuming the frequency remains constant, what happens to the wavelength in the glass as the index of refraction decreases?

Question

Quizplus · Accepted Answer

The speed of light in a medium is inversely proportional to the index of refraction. As the index of refraction decreases, the speed of light in the glass increases, leading to an increase in wavelength since frequency remains constant.
