A monochromatic (single frequency, single wavelength) light ray in air (n = 1) enters a glass prism (n = 1.5). In the glass prismGroup of answer choicesboth the frequency and the wavelength are the same as in airthe frequency is the same, but the wavelength is greater than in air.the frequency is the same, but the wavelength is smaller than in air.the wavelength is the same, but the frequency is greater than in air.the wavelength is the same, but the frequency is smaller than in air.

Laser light of wavelength 785 nm in air travels from air (index of refraction = 1) into a glass block (index of refraction = 1.5). The frequency of the light does not change when the light enters the glass. How does the wavelength of the light change, if at all, when the light enters the glass, and what reasoning supports this claim?

A monochromatic light wave with wavelength λ1 and frequency ν1 in air enters another medium. If the angle of incidence and angle of refraction at the interface are 45° and 30° respectively, then the wavelength λ2 and frequency ν2 of the refracted wave are:

The shorter the wavelength of light, the higher its frequency.
