Final answer:
The amount of refraction of light as it passes between two media depends on the indices of refraction and the change in the speed of light in the different media, which is explained by Snell's Law.
Step-by-step explanation:
The amount of refraction that occurs as light passes between two media depends on the indices of refraction of the respective media and the speed of light in each medium. When a ray of light moves from one medium to another with a different refractive index, it changes path due to refraction. The path of light bends towards the normal (an imaginary line perpendicular to the surface at the point of incidence) when it passes into a medium with a higher index of refraction, indicating that light travels slower in this medium. Conversely, when light enters a medium with a lower index of refraction, the light bends away from the normal, showing that it travels faster in this medium. This behavior can be explained using Snell's Law, which relates the change in angle of incidence to the indices of refraction for two media at an interface.
