Index of Refraction
Description:
The index of refraction is a property of a material that describes how light bends (refracts) when it passes through it. It is the ratio of the speed of light in a vacuum to the speed of light in the medium.
Senses and Usages:
- Physics: In physics, the index of refraction is a fundamental property used to determine how much light is bent when passing through a transparent medium.
- Optics: In optics, the index of refraction is commonly used to calculate the direction and degree of bending of light when it passes from one medium to another.
Sample Sentences:
- The index of refraction of water is approximately 1.33.
- When light enters a denser medium, such as glass, it experiences a higher index of refraction.
- The index of refraction affects the speed of light in a material.
