The frequency of monochromatic light ($f$) can be calculated using the formula for the energy of a photon: $E = hf$, where $E$ is the energy of the photon, $h$ is Planck's constant, and $f$ is the frequency of the light. Rearranging the formula to solve for frequency gives $f = \frac{E}{h}$. Substituting the given values, $f = \frac{4.3 \times 10^{-19}}{6.63 \times 10^{-34}} = 6.5 \times 10^{14} \, \text{Hz}$.
