Refraction is the change in direction of propagation of a wave when the wave passes from one medium into another and changes its speed. All wave types can be refracted. The normal at P is shown as a dotted line. Now that we know that the degree of bending, or the angle of refraction, is dependent on the refractive index of a medium, how do we calculate the angle of refraction?
