Решение задачи по физике раздел 2 пункт 50 оптика

50. The diffraction grating is illuminated by a parallel beam of white light. The difference between the angles of deflection of the end of the first and beginning of the second spectra (Δφ = 0°12 ´) wavelengths of extreme rays may be taken as λK = 0,76 m and λF = 0.38 microns. Determine the lattice period d.
