Formula for refractive index
WebFor light, refraction follows Snell's law, which states that, for a given pair of media, the ratio of the sines of the angle of incidence θ1 and angle of refraction θ2 is equal to the ratio of phase velocities ( v1 / v2) in the two media, or equivalently, to the refractive indices ( n2 / n1) of the two media. [2] Web10 apr. 2024 · Meaning of the statement “The refractive index of water, nw = 1.33″ This means that the ratio of the speed of light in air and the speed of light in water is equal to 1.33. Note: If the refractive index of medium x is n x and that of medium y is n y, then the refractive index of medium x w.r.t medium y is n xy = n x /n y.
