Index of Refraction Calculator

Calculate the index of refraction (n) of a medium by entering the velocity of light as it travels through that medium. Essential for optics and physics.

Index of Refraction Calculator

Must be ≤ Speed of light in a vacuum (c ≈ 299,792,458 m/s)

How to Use

  1. 1

    Enter Light Velocity

    Input the speed at which light travels through the specific medium in meters per second (m/s).

  2. 2

    Check Constraints

    Ensure the velocity entered is not greater than the speed of light in a vacuum (approximately 299,792,458 m/s).

  3. 3

    Calculate

    Click calculate to view the refractive index. A higher index means light travels slower in that medium.
