Class 12 NEET Physics Dual Nature of Matter and Radiation

Concept: Einstein explained the photoelectric effect by proposing that light energy is quantized into discrete packets called photons.Explanation:1. According to Einstein's explanation of the photoelectric effect, light behaves as a particle (photon) rather than just a wave.2. He stated that the energy ($E$) of each photon is directly proportional to the frequency ($\nu$) of the light.3. This relationship is given by the formula:$$E = h\nu$$where $h$ is Planck's constant. This concept was fundamental in proving the particle nature of radiation.Answer:A. $E=h \nu$
