WebWavelength can change, and it does so in such a way that f λ = c / n at all locations. Here f is the frequency, λ is the wavelength, c is the speed of light in vacuum, and n is the index of refraction. As you can see, going from air ( n ≈ 1) to glass (say n = 1.4) will result in the wavelength of optical light to decrease by a factor of 1.4.
