Want this question answered?
red light has the least energy of any visible (to humans) color, and violet has the most energy. The amount of energy carried by light is directly proportional to its frequency; the higher the frequency, the more energetic the light is.
Violet (purple) is the highest energy color in the visible spectrum. It has a wavelength of about 400nm (4x10-8m), the lowest of all visible light.
I suspect you mean the color with respect to light. If this is the case then red light has the lowest energy of the visible spectrum. Of course visible light is just a small part of the electromagnetic spectrum, for example, infrared light has even less energy. The lowest energy would be found in radio waves. Also it is important to realize that color is just a convention, it has no real physical meaning. Some other animal might see totally different colors.
Violet light has the highest energy.
The color red is the longest wavelength in the visible light spectrum because the less energy a wave carries the longer the wavelength and red carries the least energy of all the colors in the visible spectrum
Red
Wavelength, Frequency, or Photon Energy
Red, because it has the lowest frequency in visible light
The last color you can see at the red end has the lowest frequency,longest wavelength, least energy per photon.The last color you can see at the violet end has the highest frequency,shortest wavelength, most energy per photon.
Red light.
highest energy: violet lowest energy: red
No, red is the longest wavelength of visible light, with the lowest frequency and the least energy. Violet light has the shortest wavelenght, with the highest frequency and the most energy (of visible light).
