Electron exhibiting a particle wavelength of 5.2 x 10-9 are emitted from hydrogen atoms after interaction with high energy photons. Assuming that the electrons in the hydrogen atom were in their ground state prior to interaction, determine the wavelength of the photon which generated the free electrons

Answered by DrBob222
E = hc/wavelength.You don't have units on that electron.

But we supposed to determinate wavelength
Are you saying that electron wavelength is invalid here?
Answered by DrBob222
No. The electron emitting the 5.2E-9 (meters?) must have been moved from the ground state to an upper energy level. So the proton must have had that minimum energy. However, I notice on re-reading the question that it speaks of FREE electrons. Perhaps I'm not on the same "wavelenth" (no pun intended) as the problem since I'm not think FREE electrons.
