Product description
A light beam from a discharge tube filled with helium is normally incident on a diffraction grating with a period of 2 μm. What wavelength difference can this grating resolve in the red light region (λ1 = 0.7 µm) in the second-order spectrum if the grating width is 2.5 cm? At what wavelength in the second-order spectrum does the blue line (λ2 = 0.447 μm) of the third-order spectrum overlap?
