Webn 1 n 2 = sin θ 2 sin θ 1. where the geometry is as shown: So if n 1 = 1.0 and θ 1 = 20 degrees we have. n 2 = 1.51 for red light and θ 2 = 13.09 degrees, n 2 = 1.53 for blue light, and θ 2 = 12.91 degrees. As you can see from the diagram, a smaller value of θ 2 corresponds to a larger amount of refraction because it is a larger change in ... WebRefractive Index and the Speed of Light cnk kn /( ) ( / )/ Note: often people don’t write the subscript 0 on c, even when they mean c 0. The speed of light is /k.Since k becomes nk in a medium, where c 0 is the speed of light in vacuum. nc c 0 / The refractive index, n, of a medium is thus the ratio of the speed of light in vacuum to the speed of light in the medium.
