frequency of the photon emitted
« on: April 21, 2010, 09:17:46 PM »
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
