The formula for refractive index of a medium is
Here,
Explanation:
Recall the expression for frequency of light in air as a medium:
Here,
Substitute
The frequency of light is the same in any medium. However, its wavelength and velocity are different in different mediums.
Hence, the frequency of light in water is
Recall the expression for refractive index of medium:
The above expression can be re-written, if the medium is water, as
Here,
Substitute
Recall the expression for frequency of light in water as a medium:
It is written for the wavelength of light in water as
Here,
Substitute
Conclusion:
The frequency of light in air is
