WebOct 3, 2024 · The phenomenon of bending of light as it travels from one medium to another is known as refraction of light. The phenomenon of refraction shows that the speed of light is different in different media. As a ray of light moves from an optically rarer medium to an optically denser medium, it bends towards the normal at the point of incidence. WebAug 6, 2024 · The change in direction of a wave travelling through one medium to another is known as refraction. One of the most well-known occurrences is light refraction, although other waves, such as sound and water waves, can also refract. Because of refraction, we can employ optical equipment such as magnifying glasses, lenses, and prisms.

WebThe change of direction of light because of change of medium is known as Refraction or Refraction of Light. The ray of light changes its direction or phenomenon of refraction takes place because of difference in speed in different media. The light travels at faster speed in rare medium and at slower speed in denser medium. WebDec 26, 2024 · When light passes through a prism, it is separated into distinct color components. This is referred to as light dispersion. A prism is a transparent glass with two flat surfaces that are angled at an angle. A white light beam is divided into seven hues by a prism: violet, indigo blue, green, yellow orange, and red. trivandrum city population
