How do you find the energy of a de Broglie wavelength?
The relationship between momentum and wavelength for matter waves is given by p = h/λ, and the relationship energy and frequency is E = hf. The wavelength λ = h/p is called the de Broglie wavelength, and the relations λ = h/p and f = E/h are called the de Broglie relations.

What is the energy of a photon that has a wavelength of 377 nm express the energy in EV?
3.2883eV
Photon wavelength: 0.377 um or 377 nm. Photon energy: 3.2883eV.
How is the energy of a photon related to its wavelength?
The amount of energy is directly proportional to the photon’s electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon’s frequency, the higher its energy. Equivalently, the longer the photon’s wavelength, the lower its energy. Photon energy is solely a function of the photon’s wavelength.
How is photon energy related to the Planck constant?
E = h c λ {\\displaystyle E={\\frac {hc}{\\lambda }}}. Where E is photon energy, h is the Planck constant, c is the speed of light in vacuum and λ is the photon’s wavelength. As h and c are both constants, photon energy E changes in inverse relation to wavelength λ.
How are photon energies related to submicroscopic effects?
Table 1. Representative Energies for Submicroscopic Effects (Order of Magnitude Only) Photons act as individual quanta and interact with individual electrons, atoms, molecules, and so on. The energy a photon carries is, thus, crucial to the effects it has. Table 1 lists representative submicroscopic energies in eV.
When are photons with energy 5 eV incident?
Photons with energy 5 eV are incident on a cathode C in a photoelectric cell. The maximum energy of emitted photo electrons is 2 eV. When photons of energy 6 eV are incident. on C, no photoelectrons will reach the anode A, if the stopping potential of A relative to C is : 12th
