Problem

A precision atomic clock uses the hyperfine transition in cesium-133 atoms, where electrons flip their spin relative to the nucleus. This transition has a frequency of

f = 9.192631770 \times 10^9\;\text{Hz}

. During the calibration process, engineers need to determine the momentum of the photons emitted during this transition to account for recoil effects on the atoms. Find the momentum of a single photon emitted during the cesium hyperfine transition. Express your answer in SI units. *Note: Use

h = 6.626 \times 10^{-34}\;\text{J·s}

and

c = 3.00 \times 10^8\;\text{m/s}
