### Test 2 Question 4b

"Can any wavelength of light be emitted from the atoms in the lamp? Explain."
I got this question wrong and was wondering if anyone could explain to me what the correct answer is.

Thank you!

I got this right and I put: "the electron gains energy when it is excited, because it goes up an energy level. To be excited it must absorb the energy of a photon that exactly matches the delta E between energy levels."
