Possible frequencies of an electron
Could someone kindly clarify the following?
1. The problem statement, all variables and given/known data
In its ground state the atom absorbs 2.3 × 1019J of energy from a collision with an electron.
(i) Calculate all the possible frequencies of radiation that the atom may subsequently emit.
2. Relevant equations
3. The attempt at a solution
Using h as the planck constant and E being given , I obtained a frequency of 3.5 x 10^14 Hz.
But how do I determine the possible frequencies?
Highly appreciate any suggestions.
