Question

What is the frequency of light (in per seconds) that has a wavelength of 670 nm? ​

Answer 1

`f=4.47* 10^(14)\ Hz`

Step-by-step explanation:

Given that,

The wavelength of light,
`\lambda=670\ nm=670* 10^(-9)\ m`

We need to find the frequency of the light. The relation between the frequency and wavelength is given by :

`v=f\lambda`

The speed of light is equal to c.

So,

`f=(c)/(\lambda)\\\\f=(3* 10^8)/(670* 10^(-9))\\\\f=4.47* 10^(14)\ Hz`

So, the frequency of light is equal to
`4.47* 10^(14)\ Hz`.
