Tyndall's Experiment was brilliant. He got his results before Boltzmann discovered the mechanism of gas heating. We really did not understand black body radiation until Planck using Boltzmann's statistical approach figured out what happens. When Tyndall did his experiment in 1859 no one know how gases could absorb and re-radiate heat. To fully understand this we need the photoelectric effect and Compton effect. This were not established until the 1920's. Tyndall was really way ahead of his time.
