If an atom transitions from an initially excited state emitting a photon E=hf and going to the ground state, and since ΔxΔk=1 show that ΔEΔt = hbar.(adsbygoogle = window.adsbygoogle || []).push({});

So I know Ephoton=hf=hbar*sqrt(k/m) = hbar * sqrt(1/Δx*m)

and since E=pc and p=hbar*k=hbar/Δx

but I am not sure what to do from here???

Any help would be greatly appreciated.

Thank you.
