Quizplus · Accepted Answer

The wavelength distributions from a light bulb and from sunlight are different, with the light bulb distribution having much higher amounts of energy at long wavelengths. Sunlight has a continuous spectrum which includes all the colors of the rainbow, whereas light from a bulb typically has a more limited range of wavelengths with a peak in the yellow or red part of the spectrum, resulting in a different distribution of energy.
