A symmetrical confocal resonator has a length d=30cm, and the medium has refractive index n=1. Determine the frequency spacing [itex]\nu[/itex]_{F}and the displacement frequency ([itex]\Delta\varsigma[/itex]/[itex]\pi[/itex])[itex]\nu[/itex]_{F}. Determine all the resonance frequencies that lie within the band 5*10^{14}[itex]\pm[/itex]2*10^{9}Hz. [itex]\Delta\varsigma[/itex]= [itex]\varsigma[/itex](z_{1})-[itex]\varsigma[/itex](z_{2}) where z_{1}and z_{2}are the position of the mirrors

2. Relevant equations

[itex]\nu[/itex]_{F}=c/2d

3. The attempt at a solution

I can only find the resonance frequency. How can I get the phase shift [itex]\Delta\varsigma[/itex] from the length of the resonator?
