Does a photon of light contain all frequencies of light eg: white light - or do individual photons contain one frequency eg: red photons, green photons, blue photons etc? Or does each photon contain a few frequencies?

Each photon of light is of one particular energy, this is "denoted" by the wavelength of light (the number of wavelength sections in every meter traversed). The energy associated with the photon is given by E=h*C/wl h = Planck's constant, C = velocity of light, wl = wavelength of the light associated with the photon. C/wl is a way of calculating the frequency (f) of the light. (E=hf)

Each photon has its own characteristic wavelength and frequency.
