Product description

38. In the diffraction grating normal to its surface parallel light beam falls with a wavelength λ = 0,5mkm. Placed near the grating lens projects the diffraction pattern on a flat screen remote from the lens on the l = 1 m. The distance b between the two first-order intensity maxima observed on the screen is equal to 20,2 cm
Define:
1. constant d of the diffraction grating;
2. The number n of strokes per 1 cm;
3. The number of maxima, which thus gives a diffraction grating
4. The maximum deflection angle of φmax ray diffraction peak corresponding to the last.
