Final answer:
The energy of a photon with a frequency of 650 Hz is 4.29 × 10^-31 J.
Step-by-step explanation:
The energy of a photon is determined by the formula E = hf, where E signifies energy, h is Planck's constant (6.626 × 10^-34 J·s), and f denotes the frequency of the photon. With a given frequency of 650 Hz, substituting these values into the formula yields E = (6.626 × 10^-34 J·s) × (650 Hz), resulting in an energy calculation of 4.29 × 10^-31 J. This fundamental relationship between energy and frequency is pivotal in quantum mechanics and plays a crucial role in understanding the behavior and characteristics of electromagnetic radiation.
