How does the energy carried by a red photon with wavelength 750 nm compare to that carried by a yellow photon with wavelength 500 nm?

    The red photon would have only 0.67 times the energy of the yellow photon.
     The red photon would have three times more energy.
     The red photon would have 1.5 times more energy.
     You would have to know the speed at which the photons travel to determine this.
     They would both have the same energy.
