Einstein won the Nobel Prize in Physics in 1921 for his explanation of the photoelectric effect, not for his more famous theory of relativity.
The photoelectric effect occurs when electrons are emitted from a material after absorbing light energy. Einstein proposed that light consists of photons, and electrons are ejected only when photon energy exceeds a material-specific threshold frequency, regardless of light intensity.

In the equation E = hν, E represents the energy of a photon, h is Planck's constant (6.626 × 10^-34 Js), and ν (nu) is the frequency of the light.
The photoelectric equation is Kmax = hν - φ, where Kmax is the maximum kinetic energy of ejected electrons, hν is the photon energy, and φ is the work function of the material.
Einstein's explanation introduced the quantum theory of light and energy quantization, demonstrating that light can behave as particles (photons). This laid the groundwork for quantum mechanics and the concept of wave-particle duality.
Key SAT topics include energy quantization, the electromagnetic spectrum, light frequency interactions with matter, and applying the photoelectric equation to solve physics problems.
Wave-particle duality describes how light exhibits both wave-like and particle-like properties. Einstein's work on the photoelectric effect provided evidence for the particle nature of light.
