The frequency of the light wave remains unchanged irrespective of the medium. The speed of light changes as it moves between media. It is defined as n cv where c is speed of light in vaccum and v is velocity of light in the.
Next determine the angle of refraction.
V_ 1 is the speed of light in a vacuum. Entering these values in the. How to calculate index of refraction. It is defined as n cv where c is speed of light in vaccum and v is velocity of light in the.
