Dispersion The phenomenon of splitting of visible light into its component colors is called dispersion . Dispersion of light is caused by the change of speed of light ray (resulting in angle of deviation) of each wavelength by a different amount. The dispersion of a light wave by a prism is shown in the diagram. As white light is incident on a glass prism, the emergent light appears to be multicolored (violet, indigo, blue, green, yellow, orange and red). The light that bends the least is red ... Dispersion of Light happens when white light is split into its constituent hues due to refraction. Dispersion of Light can be achieved through various means but the most common way to achieve dispersion of light is through Prism. Dispersion of light by a prism results in the breaking of white light into its seven constituents. Definition of Dispersion of Light A white light gets amazingly separated into different colors when it strikes a special medium like glass prisms. This phenomenon of light is known as the dispersion of light . Main reason for this to happen is the differing wavelengths of various colors. Learn how white light is separated into its colors by refraction and Snell's law, and how this phenomenon is applied to natural phenomena like rainbows and Newton's rings. Explore problems and solutions on dispersion of light through prisms and other media.
