5. At normal incidence of light on the diffraction grating on the screen using a lens (focal length F = 0,8 m) observed diffraction pattern. The red line (λ = 630 nm) in the spectrum of the second order is observed at an angle φ = 11 °. Determine: 1) the lattice constant; 2) a linear grating dispersion D.
Detailed solution. Decorated in Microsoft Word 2003. (Target decided to use formula editor)
