Refractive index bitesize
WebSep 22, 2015 · Refraction is a property of waves. A wave can have different velocities for different mediums. The change of velocity at a boundary of a medium causes a wave to refract. This article is particularly focused in … WebThe refractive index n of a medium (e.g., water, olive oil, etc.), also called the index of refraction, is defined as the quotient of the speed of light in vacuum c and the speed of light in the medium v. It is a dimensionless number that depends on the temperature of the medium and the wavelength of the light beam.
