Answer:
5.98*10^(-3)mStep-by-step explanation:

The frequency of the photon is:


f=5.02*10^(10)Hz

The speed of the photon is:


v=3.0*10^8\text{ m/s}

The wavelength is calculated below


\begin{gathered} v=\lambda f \\ \\ \lambda=(v)/(f) \\ \\ \lambda=(3*10^8)/(5.02*10^(10)) \\ \\ \lambda=5.98*10^(-3)m \end{gathered}
