Answer:

Frequency,
f=4.22* 10^(14)\ Hz

Step-by-step explanation:

Given that,

Wavelength of the light,


\lambda=7.1* 10^2\ nm=7.1* 10^2* 10^(-9)\ m\\\\\lambda=7.1* 10^(-7)\ m

We need to find the frequency of light. We know that light is an electromagnetic wave. It moves with the speed of light. So,


c=f\lambda

f is the frequency of light


f=(c)/(\lambda)\\\\f=(3* 10^8\ m/s)/(7.1* 10^(-7)\ m)\\\\f=4.22* 10^(14)\ Hz

So, the frequency of light is
4.22* 10^(14)\ Hz. Hence, this is the required solution.
