Compute the speed that a gas phase oxygen molecule would have if it had the similar energy of an infrared photon λ=5000nm,a visible photon λ=500nm, a UV photon λ=100nm, an X-ray photon λ=0.1nm. Use the RMS speed for a molecule√3kT/M
What temperature would the oxygen molecule have to be to have the similar energy as the above photons?
