>For other uses, see Halloween (disambiguation). Halloween is an observance celebrated on the night of October 31, most notably by children dressing in costumes and going door-to-door collecting candy. It is celebrated in much of the Western world, though most common in the United States, Puerto Rico, Ireland, the United Kingdom, Canada and sometimes in Australia and New Zealand. Irish, Scots and other immigrants brought older versions of the tradition to North America in the 19th century. Most other Western countries have embraced Halloween as a part of American pop culture in the late 20th century. See more at Wikipedia.org...

>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.
