- What is the wavelength of a photon with frequency f= 5x10^14 Hz??What is the energy of a photon if it's frequency is 1.00s-1?By Thomson's time, it was known that excited atoms emit light waves of only certain frequencies. In his model, the frequency of emitted light is the same as the oscillation frequency of the electron or electrons in the atom. What would the radius of a Thomson-model atom have to be for it to produce red light of frequency 4.55×1014 HzHz ? (see Appendix FF from the textbook for data about the electron)
