Black Body Radiation is the phenomenon where an ideal object absorbs all incoming light and emits energy depending on its temperature. Learn about Stefan-Boltzmann Law, Wien’s Displacement Law, and Planck’s Quantum Theory through neat handwritten notes. Photoelectric Effect is the emission of electrons from a metal surface when light strikes it, covering threshold frequency, stopping potential, and Einstein’s equation (E = hf = φ + Kmax). Compton Effect explains the scattering of X-rays or gamma rays by electrons, resulting in a wavelength shift, and includes photon momentum, scattering angle, and the Compton equation (Δλ = h/mec (1 - cosθ)). De Broglie Hypothesis introduces the wave nature of matter, showing how wavelength relates to particle momentum (λ = h/p) with electron diffraction experiments. Heisenberg Uncertainty Principle states that it is impossible to measure a particle’s exact position and momentum simultaneously, explaining the fundamental quantum limits (Δx · Δp ≥ h/4π). All concepts are explained in colorful, handwritten notes, perfect for exam revision and quantum mechanics study.
