The clectron in a hydrogen atom, originally in level n=9, undergoes a transition to a lower level by emitting a photon
of wavelength 384 nm. what is the final level of the electron?
c = 3.00 x 10 m/s,
h = 6.626 x 10^-34j-s,
rh= 2.179 x 10^-18

= 9, 
= ?
Js
m/s
= wavelength ![\Delta E = -2.179 \times 10^{-18} J \times (Z)^{2}[\frac{1}{n^{2}_{2}} - \frac{1}{n^{2}_{1}}]](/tpl/images/0432/3307/57fbb.png)
![-2.179 \times 10^{-18} J \times (Z)^{2}[\frac{1}{n^{2}_{2}} - \frac{1}{n^{2}_{1}}]](/tpl/images/0432/3307/1f28d.png)
= ![-2.179 \times 10^{-18} J \times (1)^{2}[\frac{1}{n^{2}_{2}} - \frac{1}{(9)^{2}}]](/tpl/images/0432/3307/e4713.png)
