An electron in the hydrogen atom makes a transition from an energy state of principle quantum number n to the n=1 state. If the photon emitted has a wavelength of 95nm, what is the value of n?
On this problem I tried using the equation 1/wavelength = R (1/n^2 - 1/n^2)
= 1/ (9.5x10^8m) = 1.097x10^7 m^-1 (1/1 - 1/n^2)
