Calculate the frequency of violet light if the wavelength in air is 430nm.

* speed. of violet light in the prism = 2×10^8 m/s
* 1nm = 10^-9
* velocity of light in air = 3×10^8 m/s

Explanation:

Given that,

Wavelength,

We need to find the frequency of the violet light.

We know that the relation between frequency and wavelength is given by :

So, the frequency of violet light is .
