Photoelectric Effect and the Particle Nature of Light. In 1905 Albert Einstein (1879–1955) proposed that light be described as quanta of energy that behave as particles. A photon is a particle of electromagnetic radiation that has zero mass and carries a quantum of energy.

Dual Nature of Radiation and Matter Important Questions for CBSE Class 12 Physics Photoelectric Effect. 1.Photoelectric Effect The phenomenon of emission of photoelectron from the surface of metal, when a light beam of suitable frequency is incident on it, is called photoelectric effect. 30 Nov 2020 The energy of the incident photon is Ef=hf=hc/λ,, where we use fλ=c. To obtain the maximum energy of the ejected electrons, we use Equation 6.3.

The photoelectric effect is applied in devices called photoelectric cells, which are commonly found in everyday items (such as a calculator) that use the energy of light to generate electricity. Photoelectric cells convert light energy into electrical energy, which powers this calculator. If λ < λ Th, then the photoelectric effect will take place and ejected electron will possess kinetic energy. If λ = λ Th, then just photoelectric effect will take place and kinetic energy of ejected photoelectron will be zero. If λ > λ Th, there will be no photoelectric effect. Work Function or Threshold Energy (Φ) 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. Because wavelength (λ) is c / v, the equation can be simplified to p = h / λ, so a photon has momentum even though it has zero rest mass.
