Thread: Possible frequencies of an electron

Hi
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 × 10–19J 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
E=hf

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.

The energy of the emitted photon cannot exceed the collision energy, so that the frequency of the emitted photon will be Hz...

So will any frequencies less than 3.5 suffice? The answers were 0.3 and 3.2.

After the collision the electron will jump from a quantum state to another quantum state with greater energy, so that the energy badged requires that...

... where is the collision energy, the energy gap between the initial and final state and the frequency of the emmitted photon. In order to answer Your question one has to know the possible quantum state of the electron...
