How do you do this problem, I want to know how to set it up for a quiz tomorrow.
An electron moves from n=5 to n=1 quantum level and emits a photon with an energy of 2.093x10^18 J. How much energy mist the atom absorb to move an electron from n=1 to n=5? What is the wavelength of this energy?
Thanks

bobpursley,
The amount of energy from 5 to 1 is the same as 1 to 5. Wavelength? E=hf=hc/lambda
