Explain what is meant by photoelectric effect. Explain how the photoelectric effect gives evidence for this phenomenon. Figure shows the maximum kinetic energy of the emitted photoelectrons as th...
photoelectric effect is aphenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation.
The photoelectric effect provides evidence for the particle-like nature of light because the effect can only be explained by treating light as a collection of particles, or photons, that carry energy. It also supports the idea of quantized energy levels in atoms, where only specific photon energies can excite electrons to higher energy...
