>For other uses, see Light (disambiguation). 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), which is related to the human perception of brightness of the light,frequency (or wavelength), perceived by humans as the color of the light, andpolarization (or angle of vibration), which is 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.

ternate meanings: Cave (disambiguation)This article is about natural caves; for artificial caves used as dwellings, such as those in north China, see yaodong.A cave is a natural underground void large enough for an adult human to enter. Some scientists stipulate that it must be large enough that some portion of it will not receive daylight; however, in popular usage, the term includes smaller spaces like cliff cavities, rock shelters and sea caves. Speleology is the scientific exploration and study of all aspects of caves. The act of exploring a cave for recreation is called 'caving', 'potholing', or (only in the USA) 'spelunking'.
