Einstein's Photoelectric Equation

आइंस्टीन का प्रकाशवैद्युत समीकरण

In Class 12 Physics, this topic from Chapter 11, “Dual Nature of Radiation and Matter,” explains Einstein’s photoelectric equation and how it connects the energy of an incident photon with the metal’s work function and the maximum kinetic energy of emitted electrons. Students learn the roles of frequency, threshold frequency, and stopping potential, interpret the equation and related graphs, and use it to understand why the photoelectric effect supports the particle nature of light.
