8. A Fabry-Perot interferometer is assembled by two highly reflecting mirrors with a separation distance of 0.8 cm in air. The mirrors have the amplitude reflection coefficient of r = 0.932. A light source of 640063b4ed604fceb.jpg wavelength illuminates the Fabry-Perot interferometer.

(c) (6%) Determine the half-width and the contrast factor C =(It/Ii)max/(It/Ii)min.(It and Ii are the irradiances of the transmitted and incident beams.)
