Example: Consider a ray of light traveling from a medium of refractive index n1 into a medium of refractive index n2. Let θ be the angle between the initial direction of the ray and the normal to the interface between the two media.
Then, the law of refraction states that the angle of incidence is equal to the angle of refraction, or θi = θr. This can be written in terms of angles in the two media as:
sin(θi1) / sin(θr1) = n2 / n1
Here, θi1 is the angle of incidence in the first medium, and θr1 is the angle of refraction in the first medium.
This equation can be used to calculate the angle of refraction for any given set of angles and refractive indices. For example, if we know that a ray of light is incident at an angle of 30° on a surface between two media with refractive indices of 1.5 and 1.7, we can use this equation to find the angle of refraction.
