SUMMARY
The photon energies in visible light range from approximately 1.65 eV (for 750 nm) to 3.26 eV (for 380 nm). For FM radio, specifically at a frequency of 100 MHz, the energy of an FM photon is calculated using the equation E=hf, resulting in an energy of about 4.14 x 10-6 eV. The relevant equations include E=hf and the relationship between energy and wavelength, which is crucial for determining photon energies across different frequencies.
