WebThe refractive index of a medium is defined as how the light travels through that medium. It is a dimensionless measure. It defines how much a light ray can be bent when it enters … WebRefractive index, n, is a measure of how fast light travels through a substance. It is defined mathematically by Equation 1. As light moves from one medium to another, such as from air to water, it refracts at the interface and changes direction according to Snell’s Law, given as Equation 2 and shown in Figure 1. WebThe formula of the refractive index is as follows: n = c v Where, n is the refractive index c is the velocity of light in a vacuum ( 3 × 10 8 m/s) v is the velocity of light in a substance The vacuum has a refractive index of 1. The refractive index of other materials can be calculated from the above equation. keychron k8 non backlight

Sorted by: 1. The most accurate way to do this simply would be to use the Brewster angle. You set up your sample with a laser that is polarized perpendicular to the surface; then you measure the reflection as a function of angle of incidence. You get a clear null in the reflection at just one angle - the Brewster angle.
