Which of the following colors of light has the highest energy? question options: blue red violet

I believe the answer is red, they have the longest wavelength, and energy.
Hope this helps 

Violet has the highest energy (aka frequency) of all visible light. It is just below ultraviolet (UV) which is invisible.
Frequency is indirectly proportional to wavelength, so higher the energy lowest the wavelength.
