For visible light, explain how wavelength and energy vary for the different colors. Provide the trends in wavelength for the spectrum of light (purple to blue to green to yellow to orange to red). How is this different for energy?

See explanation

Explanation:

If you look closely at the image attached, you will discover that the order of increasing wavelength in the visible spectrum is;

violet < indigo< blue < green < yellow < orange < red

On the order hand, the energy of the photons increases in the order;

Red < orange < yellow < green < blue < indigo < violet

Since energy follows a trend opposite to that of wavelength, we can see that the greater the wavelength of light, the lower the energy of photon corresponding to that particular colour.
