Solve the all parts of following problem given below:
Problem: Light with a wavelength in vacuum of 514 nm falls perpendicularly on a biological specimen that is 1.50 µm thick. The light splits into two beams polarized at right angles, for which the indices of refraction are n1 = 1.320 and n2 = 1.333, respectively.
Part I: Calculate the wavelength of each component of the light while it is traversing the specimen.
Part II: Calculate the phase difference between the two beams when they emerge from the specimen.
