- Ee = 2.5 MHz *6.62*10 (-34) J*s - 2.4 eV. Ee = 2500000 1/s *6.62*10 (-34) J*s -3.4*10 (-19) J. Ee = -3.4*10 (-19) J = -2.12 eV. Given that the work function is greater in magnitude than the energy obtained by the electrons from the incident light, there will be no current generated.

- To explain the photoelectric effect, 19th-century physicists theorized that the oscillating electric field of the incoming light wave was heating the electrons and causing them to vibrate, eventually freeing them from the metal surface. This hypothesis was based on the assumption that light traveled purely as a wave through space.

- 5. Einstein’s photoelectric equation (a) For a given intensity, stopping potential depends on frequency. If v 2 > v 1, V s2 > V s1 (b) Maximum, velocity of emitted electrons v max = \(\sqrt{\frac{2 h\left(v-v_{0}\right)}{m}}\) (c) v 01 – threshold frequency of metal (1) v 02 – threshold frequency of metal (2)

- Equation of Photoelectric Effect. The photon’s energy is equal to the sum of the metal’s threshold energy and the photoelectron’s kinetic energy. Thus, the equation of photoelectric wave is given by, KE max =hv–ϕ. where, KE max is the maximum kinetic energy of the photoelectron; hv is the energy of the photon. φ is the work function of the metal
Photoelectric effect - Wikipedia
- https://en.wikipedia.org/wiki/Photoelectric_effect
- The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material.Electrons emitted in this manner are called photoelectrons. The phenomenon is studied in condensed matter physics, and solid state and quantum chemistry to draw inferences about the properties of atoms, molecules and solids. The effect has found use in …

- Formula. For black-and-white photography, the developer is typically a mixture of metol (monomethyl-p-aminophenol hemisulfate), phenidone (1-phenyl-3-pyrazolidinone) or dimezone (4,4-dimethyl-1-phenylpyrazolidin-3-one) and hydroquinone (benzene-1,4-diol). These are made up in aqueous solution with a suitable alkaline agent such as sodium carbonate, borax, or sodium …

- From Planck’s equation: Wavelength λ = (hc)/E g λ = (4.135×10 –15 eV.s x 3×10 8 m/s)/1.12 eV = 1110 nm This means that photons corresponding to infra-red wavelengths longer than 1110nm do not have enough energy to energize an electron up from the valence band to the conduction band; thus silicon is transparent above 1100nm.
