What is the third longest wavelength in the absorption spectrum of hydrogen?
Express your answer to four significant figures and include the appropriate units.
The Rydberg formula is:
R=Rydberg constant
Consider the atom is on the fundamental state when excited: n1=1
The third wavelength will be for n2=4: ~97.2018*10-9 m.
