Reflection of Light
Reflection is the process by which light bends or reflects back when it encounters a surface. When light strikes a surface, it can either reflect or absorb the energy and continue in a different direction.
Refraction of Light
Refraction is the process by which light bends when it passes from one medium to another. This can cause light to be refracted, meaning it is bent, or reflected.
Total Internal Reflection
Total internal reflection is a type of refraction in which light is completely reflected back into a medium from a more dense medium to a less dense medium. This can only occur when the angle of incidence is greater than the critical angle, which is the angle of incidence at which light would be completely reflected back into the denser medium.
Examples of Reflection and Refraction
When sunlight strikes a mirror, it is reflected back due to reflection.
When light enters a glass of water, it refracts, bending towards the normal.
When light strikes a prism, it refracts and separates into different colors due to the different angles of refraction for different colors
