... Refractive index is a measure of the amount of refraction after a boundary Refractive index = c ÷ v (where c = speed of light in a vacuum, v = speed of light in the medium. e.g. glass) Dispersion happens when light is refracted. This is where refraction splits light into all the spectral colours and ...
