Explanation:
⇒μ
μ medium
μ medium
μ medium = speed of light in given medium
μ medium = speed of light in given mediumspeed of light i nvacuum
Here refractive index of medium is inversely proportional to speed of light in the medium. As refractive index of vacuum is 1, speed of light is always greater in vacuum as compared to transparent medium. Hence, refractive index of transparent medium is always greater than one.
