Answer:
Frequency, [tex]f=4.22\times 10^{14}\ Hz[/tex]
Explanation:
Given that,
Wavelength of the light,
[tex]\lambda=7.1\times 10^2\ nm=7.1\times 10^2\times 10^{-9}\ m\\\\\lambda=7.1\times 10^{-7}\ m[/tex]
We need to find the frequency of light. We know that light is an electromagnetic wave. It moves with the speed of light. So,
[tex]c=f\lambda[/tex]
f is the frequency of light
[tex]f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8\ m/s}{7.1\times 10^{-7}\ m}\\\\f=4.22\times 10^{14}\ Hz[/tex]
So, the frequency of light is [tex]4.22\times 10^{14}\ Hz[/tex]. Hence, this is the required solution.
