Ah2 molecule can be approximated by a simple harmonic oscillator having a spring constant k = 1.1 ✕ 103 n/m.

(a) how many different energy transitions are possible when the h2 molecule decays from the third excited state down to the ground state?

i know the answer is 3

(b) find the photon energies produced in these transitions and their wavelengths. enter 0 in any unused boxes.

relative energyy transition enery wavelengths
lowest ? ?
middle ? ?
highest ? ?
i have to fill in where the ? 's are. can anyone ?
