Web15 dec. 2024 · Einstein's explanation of the photoelectric effect helped establish the quantum model of light. Each light bundle, called a photon, has a characteristic energy determined by its frequency of vibration. The energy (E) of a photon is given by Planck's law: E = hf, where f is the frequency and h is Planck's constant (6.626 × 10 −34 joule∙second). Web(a) Coherent sources:Sources emitting waves of same frequency or wavelength having either zero or a constant phase difference are said to be coherent sources of light.
