What happens to the frequency of light when it enters glass?

The frequency is determined by the source, and it doesn't change. However, since the speed is different in different media, the wavelength changes. In passing from air into glass, the speed of light decreases, and wavelengths therefore increase.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
