... a) Calculate the thickness of the thinnest possible quarter wave plate of crystalline quartz with n0 = 1.5497, ne =1.5590 for the vacuum wavelength 486 nm. Such a plate can be made thicker if it consists of two plates sandwiched together that counteract. b) A plane monochromatic, linearly polarized ...
