Q:

# What is an example of refraction?

A:

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.

Know More

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.

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."

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.

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.
