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 Web of Sound A Web of Sound A Web of Sound is the second album by the American garage rock band the Seeds. Produced by Marcus Tybalt and released in October 1966, it contained the single "Mr. Farmer" and the 14-minute closing song "Up In Her Room". The album did not chart, though it has received generally favorable reviews from music critics. Lead singer Sky Saxon conceptualized the album's cover design depicting the four Seeds members trapped in a spider's web. "A Web of Sound" was produced by Saxon under the pseudonym Marcus Tybalt; Saxon also wrote or co-wrote all of the songs
