The refractive index of crystalline quartz for a wavelength l = 589 nm is n0 = 1.544 for an ordinary beam and ne = 1.553 for an extraordinary beam. Linearly polarized light of the indicated wavelength, occupying the spectral interval Dl = 40 nm, is normally incident on a quartz plate cut parallel to the optical axis. Find the thickness of the plate d and the direction of polarization of the incident light if the light after the plate turns out to be unpolarized.
