In this problem, we look at how to solve a problem dealing with the bending of a light wave as it changes from one medium to another. Here light moves from air t lucite. The angle of incidence is 30 degrees, and we need to use the indices of refraction and snells law to find the angle of refraction. Remember, all angles are measured from the normal (a line which is perpendicular to the surface of incidence.)

In this video, I explain how to calculate frequency and then the number of waves in a give time period give the wavelength of a beam of light. Also, there is a conversion from nanometers to meters in the problem. This problem fits in with a high school conceptual physics class.
