If you have a photon with an energy of 3 electron volts calculate the energy in joules, frequency and wavelength in nm

Do you have the conversion factors?

Did you know?

Photons, the fundamental particles of light, have energy associated with them. If a photon has an energy of 3 electron volts (eV), a useful unit in atomic and particle physics, you can calculate its energy in joules, frequency, and corresponding wavelength. To convert the energy from electron volts to joules, multiply by the conversion factor 1.6 x 10^-19 Joules/eV. Thus, the energy of the photon would be approximately 4.8 x 10^-19 Joules. Additionally, to find the frequency of the photon, divide its energy in Joules by Planck's constant (approximately 6.626 x 10^-34 J∙s). Finally, to determine the wavelength, use the equation c = λν, where c is the speed of light (approximately 3 x 10^8 meters per second), λ is wavelength, and ν is frequency. Rearrange the equation to solve for λ, and remember to convert the speed of light from meters per second to nanometers (nm) per second.
