59. On the grating normal to the surface falls parallel beam of monochromatic light (λ = 0,5mkm). Placed near the grating lens projects the diffraction pattern on the screen, located in the focal plane of the lens and the distance from it to a distance of l = 1 m. The distance between the two maxima of the first order on the screen x = 20,2 cm. To determine: 1) the lattice constant d; 2) the number n of strokes per 1 mm; 3) total number of maxima Nmax, which gives the lattice; 4) the angle φmax, under which the latter can be seen at most.
