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
I Changed a Lot of HipHopDX said, ""I Changed A Lot" lacks a “We Taking Over”-style smash single to show for the incredible hit-making power of the performers present. Something just feels off in Khaled's traditional manner of creating ubiquitous pop cultural touchstones.

The album debuted at number 12 on the "Billboard" 200, with 25,000 equivalent album units in the United States, with 19,000 copies sold in its first week. I Changed a Lot I Changed
