The frequency of violet light is about twice that of red light. How does the energy of a violet photon compare with the energy of a red photon?

The frequency of violet light is about twice that of red light. How does the energy of a violet photon compar
For photons,





E = hf





where h is Plancks constant,


f is the frequency (you might also see it referred to as 'nu' or v), so





E(red) = hf


E(vio) = h(2f)





E(vio) / E(red) = 2





So the energy of violet light is twice that of red.
Reply:Violet photon has a shorter or smaller wavelength and higher frequency and are also higher in energy than red light. A red photon has a larger wavelength, smaller frequency, smaller energy
