The electron in the n = 5 level of a hydrogen atom emits a photon with a wavelength of 1280 nm. To what energy level does the electron move?
1/wavelength = (2.180 x 10^-18/hc)x(1/n1^2-1/n2^2)
n1 = unknown
n2 = 5
Thank you, sir.
did you find that electron actually moved or did it stay in place?
A hydrogen Atom makes a transition between two energy states and emits a photon with a wavelength of 434.2nm. What is the frequency? Does anyone know how to do this?
3*10^8 / 4.342*10^-7 = frequency (units are seconds^-1)
