WebIf i is the angle of incidence of a ray in vacuum (angle between the incoming ray and the perpendicular to the surface of a medium, called the normal) and r is the angle of refraction (angle between the ray in the medium and the normal), the refractive index n is defined as the ratio of the sine of the angle of incidence to the sine of the angle … WebSep 12, 2024 · This is known as Snell’s law or the law of refraction. Refraction is simply transmission with the result that the direction of propagation is changed. Snell’s law (Equation 5.8.9) determines the angle of refraction (transmission). The associated formula for ψt explicitly is: ψt = arcsin(√μr1ϵr1 μr2ϵr2sinψi)
