Finding the energy of a photon

WebSep 12, 2024 · A photon’s energy depends only on its frequency f. Explicitly, the energy of a photon is Ef = hf where h is Planck’s constant. In the photoelectric effect, photons arrive at the metal surface and each photon gives away all of its energy to only one electron on the metal surface. WebWhen light of frequency 2.42 X 10^15 Hz is incident on a metal surface, the fastest photoelectrons are found to have a kinetic energy of 1.7eV. Find the threshold frequency of the metal. Let's explore how to use Einstein's photoelectric equation to solve such numerical on photoelectric effect. Created by Mahesh Shenoy. Sort by: Top Voted Questions

WebEinstein's E = mc^2 formula is actually a special case of the special relativity formula E^2 = p^2c^2 + m^2c^4, where p is momentum, m is rest mass, E is energy, and c is the speed of light. If you substitute 0 for m (because a photon is massless), and E = hv (the formula for the energy of a photon), you get hv=pc. WebIf the photon's wavelength is known, the photon's energy can be calculated using the formula E = h c λ. h is planck's constant, c is the speed of light, and λ is the wavelength of the radiation are all represented in the equation. Hence, we can calculate the energy of photon by using either E = h f or E = h c λ.
