As light travels from vacuum (n = 1) into glass (n > 1), doesthe wavelength of t

Question

As light travels from vacuum (n = 1) into glass (n > 1), doesthe wavelength of the light change?

Yes
No Hint: When electromagneticwaves travel through a medium, the speed of the waves in the mediumis v = c/n, where n is the index of refraction of the medium. When an EM wave travels from one medium with index of refractionn1 into another medium with a different index ofrefraction n2, then its frequency remains the same, butits speed and wavelength change. For air n is nearly equal to1.

Explanation / Answer

Wavelength of the light changes. Since wavelength = speed of light / frequency frequency is not change when it passes from one medium toanother. But the speed of light changes when light passes fromone medium to another. Therefore wavelength is changes
