white light science definition
- Electromagnetic radiation composed of a fairly even distribution of all of the frequencies in the visible range of the spectrum, appearing white to the eye. Light from the Sun is nearly perfect white light, although the Sun does not itself appear white when viewed on Earth due to the scattering of light with frequencies in the blue range by the atmosphere, leaving the Sun with a yellow color.
- Light that appears white to the eye, composed of some combination of light with frequencies in the red, blue, and green parts of the spectrum. See also color.
