An “excited” atom gives up its excess energy by emitting a<br />
photon of characteristic frequency. The average period that<br />
elapses between the excitation of an atom & the time it radiates<br />
is 1.0x10 -9 s. find the uncertainty in the frequency of the photon.<br />
ΔE≧ /2Δt=5.3x10 -27 J<br />
Δν=ΔE/h = 8x10 6 Hz<br />
