question 49

Short Answer

Given that the energy levels of the hydrogen atom are given by $E _ { n } = \frac { R c h } { n ^ { 2 } }$ , where $R = 1.097$ $\times 10 ^ { 7 } \mathrm {~m} ^ { - 1 }$ , what wavelength photon is emitted when the atom undergoes a transition from the $n = 4$ to the $n = 6$ level?
