Light refraction is the bending of light as it passes between different media, influenced by the refractive index. This text explores the fundamental laws of refraction, including Snell's Law, and phenomena such as total internal reflection and the critical angle. It also discusses practical applications in lenses, cameras, and the natural spectacle of rainbows, highlighting the importance of refraction in optical technologies and everyday life.

The ratio of the speed of light in a vacuum to its speed in a given material, determining the degree of bending of light
First Law
The incident ray, refracted ray, and normal to the interface all lie in the same plane
Second Law (Snell's Law)
The angles of incidence and refraction are related to the refractive indices of the two media
Occurs when light attempts to pass from a medium with a higher refractive index to one with a lower refractive index at an angle greater than the critical angle
Lenses manipulate light through refraction for various applications such as eyeglasses, cameras, and telescopes
Refraction causes the separation of white light into its component colors, as seen in rainbows
Mathematically expresses the relationship between angles and refractive indices in refraction
The path taken by light between two points is the one that can be traversed in the least time
The angle at which total internal reflection occurs, calculated using the refractive indices of the two media
