Co2 absorption band
WebApr 25, 2014 · The visible is 0.4-0.8 microns, the CO2 absorbtion band is centered at 15 micron and with a width of 2 microns (14-16 microns, in reality it is much narrower than this). You end up with a ratio of the energy coming from the sun in the CO2 related absorption band and the visible of the order of 10^-4. Negligible. WebSo: CO 2 speed: 400 km/h ~ 111 m/s. Photon speed: 299,702,547 m/s. If the direction of the two objects is the same, the CO 2 molecule perceives the photon's frequency as 1.00000037 times its real frequency. If both objects move in the opposite direction the perceived frequency is 0,99999963 times the real frequency.
