25/04/19 Sodium doublet has lines of 589 nm and 589.59 nm in its spectrum I got 999 for the resolving power required for a diffraction grating if these lines to be distinguished (not sure it is right please check). 99,500 lines of the diffraction grating must be illuminated in order to resolve the second order spectrum, please can you explain why this is?

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...

A diffraction grating with 155 slits per centimeter is used to measure the wavelengths emitted by hydrogen gas. At what angles in the third-order spectrum would you expect to find the two violet lines of wavelength 434 nm and of wavelength 410 nm? (angles in radians) The 434 nm line: [5 points] 2 attempt(s) made (maximum allowed for credit = 5) [after that, multiply credit by 0.5 up to 10 attempts] The 410 nm line:
