Homework Help: Physics

Posted by Joe on Tuesday, April 19, 2011 at 9:14pm.

A hydrogen atom initially in its ground state (n = 1) absorbs a photon and ends up in the state for which n = 3.

What is the energy of the absorbed photon?

*I found the energy of the atom at the ground state and at n = 3. I subtracted the final from the initial to get a value of 9.1 eV but it wasn't correct. Am I doing this correctly?
