What is Refractive Index?
In optics, the refractive index (also known as refraction index or index of refraction) of a material is a dimensionless number that describes how fast light travels through the material. It determines how much the path of light is bent, or refracted, when entering a material and varies with wavelength, this causes white light to split into constituent colors when refracted. The concept of refractive index applies within the full electromagnetic spectrum, from X-rays to radio waves. It can also be applied to wave phenomena such as sound.
How to Calculate Refractive Index?
Refractive Index calculator uses Refractive Index = sin(Angle of Incidence)/sin(Angle of Refraction) to calculate the Refractive Index, The refractive index is defined as how the light travels through a medium. It is a dimensionless measure. It defines how much a light ray can bend when it enters from one medium to the other. Refractive Index is denoted by RI symbol.
