The sodium spectrum is dominated by the bright doublet known as the Sodium D-lines at λ1=588.995 and λ2=589.5924 nanometers. Say, you've got a diffraction grating with 3900 grooves/cm. Find the angles corresponding to the maxima of λ1 and λ2 in the first order: ° and ° Find the difference between these angles: °. Now do the same for the second order: °, °, and °. Notice that the resolution increases with the order! In what maximum order can these lines be observed?

The bright yellow sodium line in the sodium spectrum is actually
a pair of closely spaced lines at 589.0 nm and 589.6 nm. You
observe the sodium spectrum using a diffraction grating with a
spacing of 1700 nm . Find the angular separation between the two
sodium lines in first order. Find the angular separation between
the two sodium lines in second order. Express your answer to two
significant figures and include the appropriate units.

The line spectrum of helium has many more lines in it than the
line spectrum of hydrogen. Draw orbital energy diagrams for both H
and He, showing all orbitals up through n = 3. Use these diagrams
to explain why helium’s line spectrum is so much more complex. They
should differ in more than just the number of electrons!

Laser light of some wavelength λ1 shines on a diffraction
grating with 285 lines/mm at normal incidence, producing a pattern
of maxima on a large screen 1.50 m from the grating. The first
principal maximum is observed to be at an angle of 8.20° from the
central maximum.
