Which of the following is correctly matched?

View answer and explanation

Correct option: A

Momentum of H atom when electrons return from n=2 to n=1:

\frac{{3Rh}}{4}

Option A is correctly matched because the momentum of the H atom equals the momentum of the emitted photon when the electron transitions from n=2 to n=1, which is calculated to be

\frac{{3Rh}}{{4}}
