Task id13754

A parallel beam of natural light with intensity I0 and wavelength l falls on a system of two crossed polaroids P1 and P2 and a quartz wedge K with a small refractive angle a. The refractive indices of quartz are equal to ne and n0. The optical axis of the wedge is parallel to its edge and makes an angle of 45° with the allowed directions of the polaroids (figure). After passing through the system, light falls on a white screen E. Find the distribution of light intensity I(x) on the screen. What will the observer see on the screen E, if between him and
