Do colors on the red end of the spectra emmit more energy or do coloors on the violet end?

Colors do not "emit" energy. Colors are a result of our perceptions of different wavelengths. Shorter wavelengths have higher energy. Violet corresponds to a shorter wavelength and thus would have greater energy. Ultraviolet cannot be seen but has even greater energy, sufficient to damage your skin. X-rays are still shorter and have enough energy to pass through you.

Do colors on the red end of the spectra emmit more energy or do coloors on the violet end?
Waves of different wavelengths have different energies.



The formula E = hf, where E = energy, h = planck constant, and f = frequency of wave, sums it all.



Violet end waves have a higher frequency then red ones so by the formula E = hf, the violet waves would have a higher energy.
Reply:the violet end has a shorter wavelength, and thus higher energy
