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
Photon Energy Formula How To Find The Energy Of A …
WebA photon is a quantum of EM radiation. Its energy is given by E = hf and is related to the frequency f and wavelength λ of the radiation by. E = hf = hc λ (energy of a photon), … WebFinding the photon momentum is a straightforward application of its definition: [latex]{p = \frac{h}{\lambda}}[/latex]. If we find the photon momentum is small, then we can assume that an electron with the same momentum will be nonrelativistic, making it easy to find its velocity and kinetic energy from the classical formulas.
