- The full width at half maximum of an atomic absorption line at 589 nm is 100 MHz. A beam of light passes through a gas with an atomic density of 10^17/m3 . Calculate: (1) The peak absorption coefficient due to this absorption line. You can assume that the index of refraction is close to 1 in for this dilute gas. (2) The frequency at which the resonant contribution to the refractive index is at a maximum. (3) The peak value of this resonant contribution to the index of refraction.arrow_forward1a)A sample was excited by the 4358 angstrom line of mercury. Raman line was observed at 4447 angstrom.
