Light with wavelength `lambda = 0.60 mu m` falls normally on a diffraction grating inscribed on a plane surfcae of a plano-curvex cylinderical glass lens with curvature radius `R = 20 cm`. The period of the grating is equal to `d = 6.0 mu m`. Find the distance between the principle maxima of first order located symmetrically in the focal plane of that lens.
