A parallel beam of linearly polarized light of wavelength 589nm (in vaccum) is incident on a calcite crystal. The propagation direction is perpendicular to the optic axis..
A) find the wavelength of both extraordinary and ordinary wave in crystal.
B) find the minimum thickness of crystal necessary to produce phase differences of pi/4, pi/2, and pi between the emergent waves.
C) If the E vector in the incident light makes an anglez 45 degrees with the optic axis, what is the state of polarization of the emergent light in the three cases in part B?
