The mirrors of the Fabry-Perot interferometer, having a reflection coefficient p = 99% (in intensity), are located at a distance L = 1 m from each other. The standard is used as an optical resonator at a wavelength l = 0.63 μm. Using the analogy with an oscillatory circuit, determine the quality factor of the resonator and the width dn of the resonance curve (in megahertz). Also determine the frequency interval Dn between two adjacent resonances.
