Question

The electron in a hydrogen atom makes a transition from the n = 4 state to the n = 2 state, as indicated in the image. (Figure 1) Figure 1 of 1The figure shows a model of an atom including a nucleus and four circular orbits around the nucleus. An electron jump occurs from the fourth to the second orbit from the center. A photon moves horizontally leftward. Momentum of the photon is directed horizontally rightward, and momentum of the atom is directed horizontally leftward. Electron jump Momentum of photon Momentum, of atom

Part A Determine the linear momentum of the photon emitted as a result of this transition. p p = nothing   kg⋅m/s   SubmitRequest Answer Part B Using your result to part A, find the recoil speed of the hydrogen atom, assuming it was at rest before the photon was emitted. v v = nothing   cm/s
