Determine the energy of a photon of electromagnetic radiation with a frequency of 5 MHz .

Did you know that the energy of a photon can be calculated using the simple formula E = h * f, where E is energy, h is Planck's constant (approximately 6.63 x 10^-34 J·s), and f is the frequency in hertz? So for a frequency of 5 MHz (which is 5 x 10^6 Hz), plugging in the numbers gives you an energy of roughly 3.31 x 10^-27 joules. It’s a teeny-tiny amount of energy, perfect for the radio waves used in your favorite music stations! In the grand scheme of things, photons at this frequency are falling into the radio wave part of the electromagnetic spectrum. These waves are crucial in everyday technology, from broadcasting radio signals to communication systems. So, your next conversation with a friend over the radio might just be powered by those diminutive little photons buzzing along at 5 MHz!
