Shorter wavelengths emit more energy than longer wavelengths. Each color contains electromagnetic particles that constantly radiate energy as they travel in waves- varying in wavelength and power, and releasing different amounts of energy into the atmosphere. Sunlight consists of all different shades of red, orange, yellow, green and blue light rays, called the visible light spectrum.
