What is the refractive index?

Asked by Terra504

Answer (2)

The refractive index is the ratio of the speed of light in a vacuum to its speed in a material, indicating how much the material slows down light. Snell's law uses refractive indices to determine the direction of light when passing between materials. This concept is important in optical applications like lens design and image formation in the human eye. ;

The refractive index is the ratio of the speed of light in a vacuum to its speed in a medium, indicating how light is affected as it passes through different substances. It is crucial in applications involving optics, such as lens design and predicting light behavior with Snell's Law. Understanding the refractive index helps us comprehend phenomena like how lenses focus images and how light bends at material boundaries.
