A photon interacts with a ground state electron in a hydrogen atom and is absorbed. The electron is ejected from the atom and exhibits a de Broglie wavelength of 1.828×10−10 m. Determine the frequency (in hz) of the interacting photon.

How do you use the above data and insert into the formula?

chacho's answer is right if you have in your question de Broglie wavelength of 5.908×10−10 m :-)

please give us the formula
Chemistry - qwerty, Saturday, January 12, 2013 at 4:14pm
E = P^2/2Me + E(first ionization)

P= h / BroglieWavelength

E(first ionization)=21.7*10^-19

Me= 9.1*10^-31

h= 6.626*10^-34

frecuency(hz)= E / h

I have one question about the formula, is it E = P^2/(2Me + E)(first ionization) or E = P^2/(2Me + E(first ionization) ) ??
Chemistry - kaken, Sunday, January 13, 2013 at 8:08am
sorry i wrote the same formula; my questios was if the formula is:

1- E = (P^2/2Me )+ E(first ionization)
or
2- E = P^2/(2Me + E)(first ionization)

sorry for the previous post
