Light is electromagnetic radiation with a wavelength that is visible to the eye (visible light) or, in a technical or scientific setting, electromagnetic radiation of any wavelength. The three basic dimensions of light (i.e., all electromagnetic radiation) are:

- intensity (or brilliance or amplitude, perceived by humans as the brightness of the light),
- frequency (or wavelength, perceived by humans as the color of the light), and
- polarization (or angle of vibration and not perceptible by humans under ordinary circumstances)
Due to wave-particle duality, light simultaneously exhibits properties of both waves and particles. The precise nature of light is one of the key questions of modern physics.
