1/wavelength = (2.180 x 10^-18/hc)x(1/n1^2-1/n2^2) n1 = unknown n2 = 5

sarah · Answer

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?

Anonymous · Answer

3*10^8 / 4.342*10^-7 = frequency (units are seconds^-1)
