In this lab you will use a spectrometer to measure the wavelengths ofseveral visible lines emitted from hydrogen gas, a.k.a. the Balmer series.Sketch and label an energy level diagram for hydrogen, and draw thetransitions corresponding to the first four lines in the Balmer series (nf = 2).For the first four lines, indicate which is toward the red end of the spectrumand which is toward the purple end.

Question

In this lab you will use a spectrometer to measure the wavelengths of
several visible lines emitted from hydrogen gas, a.k.a. the Balmer series.
Sketch and label an energy level diagram for hydrogen, and draw the
transitions corresponding to the first four lines in the Balmer series (nf = 2).
For the first four lines, indicate which is toward the red end of the spectrum
and which is toward the purple end.
