1. The problem statement, all variables and given/known data Light with wavelength 500 nm is emitted from an electron in an atom behaving as a lightly damped simple harmonic oscillator with Q = 5 x 10^7. Find the linewidth (width to half-power points) in nm. 2. Relevant equations wavelength=c/f f=w/2pi Q=f/delta f=w/delta w 3. The attempt at a solution So i started by calculating frequency and then angular frequency f = 3E8/500E-9 = 6E14hz w = 6E14*2pi = 3.77E15 radians/sec I did some research and found that Q=resonant frequency/(half-power bandwidth) But how do i work out the resonant frequency? The lecturer said it would take us maybe an hour or two to solve this problem so it seems to simple for the frequency i have to be the one required here.
