Problem 6.41

A stationary hydrogen atom emits a photon corresponding to the first line of the Lyman series. What velocity does the atom acquire?

Reveal Answer
v=3ℏR/4mc=3.25 m/s, where m is the mass of the atomv=3 \hbar R / 4 m c=3.25 \mathrm{~m} / \mathrm{s}, \text { where } m \text { is the mass of the atom}
