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. WebThe refractive index of a substance is strongly influenced by temperature and the wavelength of light used to measure it. Therefore, care must be taken to control or compensate for temperature differences and wavelength.
