Oscillation that travels through a medium by transferring energy from one particle or point to another without causing any permanent displacement of the medium. Quantum of visible light or other form of electromagnetic radiation. Hue: perceptual attribute of colors that enables them to be classed as similar to demonstrating both particle and wave properties red, green or blue, or something in between. Violet at about 400nm through red at about 650nm. What happens to light on its way from a star to an eye. In empty space the electromagnetic radiation from a star travels in a straight line at the speed of light. Once it reaches the atmosphere, some of the star"s photons are absorbed by encounters with dust, vaporized water, etc and some of the light is scattered (sometimes called diffracted) by these particles.
