Expression for recoil velocity of hydrogen atom during electron transition

Click For Summary
SUMMARY

The recoil velocity of a hydrogen atom during an electron transition from the 3rd to the 1st orbit can be calculated using the principles of conservation of momentum and energy. The energy of the emitted photon corresponds to the difference in energy levels, specifically 10.2 eV for this transition. The momentum of the photon can be determined using the formula p = E/c, where E is the photon energy and c is the speed of light. Consequently, the recoil velocity of the hydrogen atom can be derived from the momentum of the photon, ensuring that the total momentum remains conserved.

Hi all
How does one calculate the recoil velocity of a hydrogen atom when the electron in it jumps from a higher orbit to a lower orbit (say from 3rd to 1st) ?
