Photoelectric Effect

This study guide covers the photoelectric effect, explaining how light behaves like a particle (photon) and ejects electrons from metal surfaces. Key concepts include Einstein's and Compton's contributions, classical vs. quantum predictions, essential formulas (e.g., E=hf, K_max = hf - Φ), work function, and threshold frequency. It also provides exam tips, practice problems (multiple-choice and free-response), and solutions. The guide emphasizes understanding the relationship between kinetic energy, intensity, and frequency of light in the photoelectric effect.
