snell's law ...change in wavelength
Asked by | 28 Jun, 2008, 03:18: PM
answered-by-expert Expert Answer

In refraction, a wave crossing from one medium to another of different density  alters its speed and direction upon entering the new medium. The ratio of the refractive indices of the media determines the degree of refraction, and is summarized by Snell's law.

Yes, it is possible that it has wavelengths in the range where the UV and violet as well as infra red and red almost overlap.
