Question

The refractive index of a medium is a. focal length to object distance b.speed of light in air to speed of light in medium c.The refractive index of a medium is d.speed of light in vacuum to speed of light in air ​

Answer 1

Answer:

Explanation: The refractive index of a medium (n) is equal to the speed of light (c) divided by the velocity of light through the medium (v). ... Light will travel faster through medium A at a velocity equal to the speed of light divided by the refractive index.
