The atomic emission spectrum of a light source is analyzed with a diffraction grating. A thick line near 589.0 nm is observed. In order to resolve the thick line into two fine lines in first order, you replace with a 2.450 cm long diffraction grating, and you barely observed two distinct first order spectral lines at 589.0 and 589.6 nm on a screen 5.000 m away. a. What is the resolving power of the grating? b. What is the slit...
Light of wavelength 429 nm (in vacuum) is incident on a diffraction grating that has a slit separation of 1.2 × 10-5 m. The distance between the grating and the viewing screen is 0.10 m.
