The first vibrational level for NaH lies at E = 1.154 x 10-20 J and the second vibrational level lies at E = 3.406 x 10-20 J. What is the frequency of the photon emitted when a molecule of NaH drops from the second vibrational level to the first vibrational level? (Calculate ΔE first.)
Need help with this. Please explain. Thank youuu
