Question
Will a photon of light of wavelength 480 nm excite an electron in the hydrogen atom from the n = 1 level to the n = 2 level?
How would I figure this out?

Energy needed to excite an electron from the n = 1 to the n = 2 level is
E = 2.18E-18 J(1/1^2 - 1/2^2)
Compare that energy needed with what you have in a 480 nm beam of light. E = hc/wavelength
Post your work if you get stuck.
