Electromagnetic radiation — these interactions include the Faraday effect and the Kerr effect. In refraction, a wave crossing from one medium to another of different density alters its speed and direction upon entering the new medium. The ratio of the refractive indices of the media determines the degree of refraction, and is summarized by Snell's law. Light of composite wavelengths (natural sunlight) disperses into a visible spectrum passing through a prism, because of the wavelength-dependent refractive index of the prism material (dispersion); that is, each component wave within the composite light is bent a different amount. EM radiation exhibits both wave properties
A Sound Garden A Sound Garden A Sound Garden is one of six outdoor public art works on the National Oceanic and Atmospheric Administration (NOAA) campus that lies adjacent to the Warren G. Magnuson Park on the northwestern shore of Lake Washington in Seattle, Washington. The Seattle Arts Commission guided the jury selection headed by Sadao James Hilario, Engineer-in-charge of the GSA Art in Architecture Program for the NOAA Project, and the jury chose five artists from a pool of more than 250. Designed and built by sculptor Douglas Hollis from 1982–83, "A Sound Garden" is a sculptural group composed of 12 21
