Given:

The wavelength of light is


\begin{gathered} \lambda\text{ = 657.61 nm} \\ =657.61*10^(-9)\text{ m} \end{gathered}

The speed is v = 232536355.7 m/s

Required: The frequency of the wave.

Explanation:

The frequency can be calculated by the formula


f=(v)/(\lambda)

On substituting the values, the frequency will be


\begin{gathered} f=\text{ }(232536355.7)/(657.61*10^(-9)) \\ =3.536*10^(14)\text{ s} \end{gathered}

Final Answer: The frequency of the wave is 3.536e14 s
