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
There's a New Sound never "kid themselves properly (or) let their voices go") by making appearances on "The Ernie Kovacs Show" and recording a full-length album, "Music to Suffer By", in the same style she used for "Fish." "There's a New Sound" was later featured often on the Dr. Demento show and performed by Scooter on "The Muppet Show". There's a New Sound "There's a New Sound" was a 1953 novelty song by Tony Burrello and Tom Murray. Burrello, a songwriter and jazz pianist, and Murray started writing novelty songs after they were unsuccessful in having their more serious-minded songs recorded by prominent musicians.
