Suppose a light source emits a Gaussian spectrum centered at wavelength = 1300 nm with a full-width half max (FWHM) bandwidth = 10 nm.

(a) Calculate the center frequency f0 of the light spectrum and the FWHM bandwidth in terms of the frequency spread f.

(b) Calculate the photon energy corresponding to the center wavelength and the FWHM bandwidth in terms of the energy spread E.
