The answer is \(2.35 \times 10^{-16} \, \text{J}\).
Using the formula:
E = hv
This equation states that the energy of a particle of light (E), known as a photon, is proportional to its frequency (v), by a constant factor (h, the Planck constant, \(6.626 \times 10^{-34} \, \text{J s}\)). This implies that photons with low frequencies, such as radio waves, possess lower energies than photons with high frequencies, such as X-rays.
Solution:
E = (6.626 \times 10^{-34} \, \text{J s}) \times (3.55 \times 10^{17} \, \text{Hz})
E = 2.35 \times 10^{-16} \, \text{J}
