Solving a problem in physics section 18 point 57 optics

57. Because you want to cut quartz plate, parallel to the optical axis of the crystal, a thickness of about 0.6 mm so that the plane-polarized beam of yellow light (λ = 0,589 m), passing record, became polarized around. Calculate the thickness of the plate, if the yellow rays in quartz refractive indices of the ordinary and extraordinary rays, respectively, are: no = 1,544, ne = 1,553.
