Question

What is the frequency of a monochromatic light used in a diffraction experiment that has a wavelength of 6.38 ✕ 10e-07 m?

Answer 1

`f=4.70* 10^(14)\ Hz`

Step-by-step explanation:

Given that,

The wavelength of light,
`\lambda=6.38* 10^(-7)\ m`

We need to find the frequency of the light. We know that,

`c=f\lambda\\\\f=(c)/(\lambda)\\\\f=(3* 10^8)/(6.38* 10^(-7))\\\\f=4.70* 10^(14)\ Hz`

So, the required frequency of light is equal to
`4.70* 10^(14)\ Hz`.
