What Happens When All the Different Spectrum Colors of Light

Question

Examlex · Accepted Answer

The Answer is When all the different spectrum colors of light are mixed together, the result is white light. This phenomenon is based on the additive color mixing principle, where the sum of all the colors of light in the visible spectrum (red, orange, yellow, green, blue, indigo, and violet) combine to produce white.

The visible spectrum of light is a small part of the electromagnetic spectrum that can be perceived by the human eye. Each color has a different wavelength, with red having the longest wavelength and violet having the shortest. When these wavelengths are combined in equal intensities, they create white light.

This is the principle behind how devices like televisions and computer monitors work. They use red, green, and blue (RGB) light-emitting elements, and by varying the intensity of each color, they can create the full range of visible colors, including white when all three are combined at full intensity.

In contrast, the mixing of pigments or dyes (such as in paint) follows the subtractive color mixing principle, where combining all colors typically results in black or a muddy brown, as pigments work by absorbing certain wavelengths of light and reflecting others.
