Refractive index angle of refraction

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 θ 1 and angle of refraction θ 2 is equal to the ratio of phase velocities (v 1 / v 2) in the two media, or equivalently, to the refractive indices (n 2 / n 1) of the two media. WebOct 28, 2015 · 1. The formula for the refractive index of a prism is: μ = sin ( A + D m 2) sin ( A / 2) However, this requires me to find out the angle of minimum deviation ( D m ).
