A plane light wave with wavelength .60 micrometers falls normally on the face of a glass wedge with reflecting angle 15 degrees. The opposite face of the wedge is opaque and has a slit of width b=10 micrometers parallel to the edge. Find:
a) the angle delta between the direction of the Fraunhofer maximum of zeroth order and that of incident
b) the angular width of the Fraunhofer maximum of the zeroth order
