Answer:


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.
