📚 Quick Study Guide

  • 💡 Wave-Particle Duality: Light exhibits both wave-like and particle-like properties.
  • 🧪 Young's Experiment: Demonstrates the wave nature of light through interference.
  • 📏 Fringe Spacing Formula: $\Delta y = \frac{\lambda L}{d}$, where $\Delta y$ is the fringe spacing, $\lambda$ is the wavelength, $L$ is the distance to the screen, and $d$ is the slit separation.
  • 🌈 Constructive Interference: Occurs when waves are in phase, creating bright fringes.
  • 🌑 Destructive Interference: Occurs when waves are out of phase, creating dark fringes.
