Red, blue, and yellow light can make white light when they are mixed together because they are primary colors that cover the entire visible spectrum. When combined in equal amounts, they create a wide range of wavelengths that collectively appear white to our eyes.
White light is composed of all the colors in the visible light spectrum, which range from approximately 430-750 THz. This corresponds to a range of frequencies from 430-750 trillion cycles per second.
The range of colors that white light can be split into is called the visible spectrum. It consists of colors such as red, orange, yellow, green, blue, indigo, and violet.
No, not all light sources have the same spectra as white light. White light contains all the colors of the spectrum, while other light sources may emit only specific colors or wavelengths, resulting in a different spectral composition.
Blue light and yellow light are complementary colors, meaning they combine to produce white light. This indicates that the two colors have wavelengths that, when combined, cover the entire visible spectrum of light.
