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. Also, the ratio of the velocity of the ray in the new medium to that in the old is given by the Snell's law: n2v2 = n1v1, where v1 and v2 are the speeds of the ray in the two media respectively.
To illustrate this, consider the following scenario: A ray of light traveling from air (n1 = 1.0) into water (n2 = 1.33). Let's say that the initial angle of incidence is 45 degrees. Using Snell's law, we can calculate the angle of refraction for this situation.
Answer: Using the given values for n1 and n2 and the angle of incidence, we can calculate the angle of refraction using Snell's law. The result will be 37 degrees. Note that the angle of refraction is less than the angle of incidence, indicating that light is bending as it travels from one medium to another.
