Refraction of light can be seen in many places in our everyday life. It makes objects under a water surface appear closer than they really are. It is what optical lenses are based on, allowing for instruments such as glasses, cameras, binoculars, microscopes, and the human eye. Refraction is also responsible for some natural optical phenomena including rainbows and mirages. WebThe refractive index, n, is dimensionless since it's a ratio. It has the formula n = c v, where c is the speed of light in vacuum and v is the speed of light in the medium. Both quantities have units of meters per second, m s. In a vacuum, the refractive index is unity, and all other media have a refractive index that is greater than one.
