Q:

What is an example of refraction?

A:

Quick Answer

The formation of a rainbow and the splitting of light when it passes through a prism are examples of refraction. A pencil placed in a beaker of water looks bent due to refraction of light.

Full Answer

When light travels from one medium to another medium, it bends a little. This bending of light is called refraction. A medium can be a solid, a liquid or a gas. The amount by which light bends depends on the properties of the medium. Refraction of white light through a prism is called dispersion of light, and it clearly shows that light is made up of seven colors. Sound waves undergo refraction, as well.

  • Q:

    What is the index of refraction?

    A:

    The index of refraction of any material is the speed of light in a vacuum divided by the speed divided by the speed of light in the medium. It is denoted with the letter "n."

  • Q:

    Why does refraction happen?

    A:

    Refraction is the bending of a beam of light when it enters a medium of different density. Light travels fastest in vacuum and in air. When light enters a medium of higher density, such as water, its velocity changes and causes it to bend or refract.

  • Q:

    What are the practical applications of refraction?

    A:

    Refraction is the differential bending of light as it passes through a medium, and it is used in a wide variety of applications throughout industry and the sciences as well as in living bodies. Light refracted through an optical prism spreads out into a spectrum of its constituent colors and allows individual wavelengths to be examined on their own.

    What is Snell's law of refraction?

    A:

    Snell's law of refraction is the relationship between the angles of incidence and refraction with respect to the refraction indices of two different media. Snell's law of refraction can be applied to the refraction light for any two media. Snell's law predicts the angle of refraction that light follows when passing from one medium and into the next medium.
