Answer:

Step-by-step explanation:

The speed of a photon is:

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

The wavelength is given as:

$\lambda=4.36*10^4m$

The relationship between speed, wavelength, and frequency is:

$v=\lambda f$

Substitute the values of v and λ, and solve for f

$\begin{gathered} 3*10^8=4.36*10^4* f \\ \\ f=(3*10^8)/(4.36*10^4) \\ \\ f=6880.7\text{ Hz} \end{gathered}$
f=6.88*10^3Hz
