1. The problem statement, all variables and given/known data Unpolarized light is reflected internally in the point P in a glass prism. When the prism is located in air, β is the critical angle of total reflection. I am going to calculate for the following problems: a) If the prism is submerged into water the reflected light becomes completely linear polarized. Determine the refractive index of the glass at the current wavelength. Assume that the water has the refractive index nv=1.33 and that the refractive index of the glass prism is greater than this(ng > nv). b) Does the result in a apply to light with arbitrary wavelengths? Why? c) Assume that you only have access to diamonds instead of glass prisms. Can you make a similar experiment as in task a? Find out a typical refractive index for diamond when the light has the wavelength λ = 550nm. 3. The attempt at a solution No attempt has yet been made, since I don't understand the sentence "Determine the refractive index of the glass at the current wavelength." in task a. This because I don't see any given wavelength. If anyone care to explain this I would be grateful!
