What happens when light waves pass at an angle from one medium to another?

When light waves pass from one medium to another at an angle, they refract or bend due to the change in speed as they move through different materials. This phenomenon occurs because light travels at different speeds in different media. For instance, light travels faster in air than in water or glass. When light enters a denser medium, it slows down and bends towards the normal, which is an imaginary line perpendicular to the surface at the point of entry. Conversely, when light exits a denser medium into a less dense one, it speeds up and bends away from the normal. This bending of light is governed by Snell's Law, which mathematically describes how the angle of incidence and the angle of refraction relate to the indices of refraction of the two media. The other choices describe different behaviors of light: it can speed up when moving to a less dense medium, scatter due to interaction with particles, or reflect when it hits a surface at the correct angle. However, the bending of light when it passes between different media at an angle best characterizes the refractive behavior of light.
