A photon of wavelength 300nm is emitted from an atom when an electron makes a transition from an energy state of -4 eV to a state of -8 eV. IF the initial state had been at enerygy of -6 eV, the wavelength of the photon emitted in a transition to -8eV is..??
The Attempt at a Solution
I don’t know the basis of this question, but here is my attempt. Since the change in energy from -4eV to -8eV is -4 eV and from -6ev to -8eV is -2, so the energy is halved. If E is halved, then I think λ doubles and the anwer would be 600nm (not sure)
