Final answer:
Refraction is the bending of light as it passes from one medium to another. It can be described using Snell's Law and is affected by the refractive indices of the two media involved. When light passes from a less dense medium to a more dense one, it bends towards the normal line, and vice versa. Diagrams can help illustrate the process of refraction.
Step-by-step explanation:
The Process of Refraction of Light
Refraction is the bending of light as it passes from one transparent medium to another with a different refractive index. The process can be described using Snell's Law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the refractive indices of the two media.
When light travels from a less dense medium (like air) to a more dense medium (like water), it bends towards the normal line. Conversely, when light travels from a more dense medium to a less dense medium, it bends away from the normal line.
Refraction can be illustrated using diagrams. For example, an incident ray of light approaching a glass slab at an angle will bend towards the normal line, and upon exiting the slab, it will bend away from the normal line.
