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

According to Snell's law of refraction, n1*sin(theta1) = n2*sin(theta2), as the index of refraction decreases, the angle of refraction increases. Therefore, the wavelength in the glass increases, leading to a decrease in frequency.
