Formula and explanation
Formula: n = (c)/(v) Applicable Conditions: Light propagating in a medium, where c is the speed of light in vacuum and v is the speed of light in the medium. Explanation: The refractive index n is a key parameter describing the optical properties of a medium, defined as the ratio of the speed of light in vacuum to its speed in the medium. A higher refractive index means light travels slower in the medium.
