Wave Interference - Interference | Double Slit | Diffraction - PhET Interactive Simulations

Make waves with a dripping faucet, audio speaker, or laser! Add a second source to create an interference pattern. Put up a barrier to explore single-slit diffraction and double-slit interference. Experiment with diffraction through elliptical, rectangular, or irregular apertures.

Introduction

Wave Interference Simulation Overview

  • Core Topics: Wave interference, double-slit experiments, and diffraction.
  • Media Types: Simulations for water, sound, and light waves.
  • Key Learning Objectives:
    • Understanding the relationship between different wave types.
    • Designing experiments to measure wave speed.
    • Analyzing interference patterns generated by two sources.
    • Identifying constructive and destructive interference points using visual observation and detectors.
    • Observing wave behavior through single and double-slit barriers.
  • Mathematical Application: Predicting light fringe locations using the formula $d \sin(\theta) = m\lambda$.
  • Experimental Variables:
    • Adjusting wavelength and aperture size to observe effects on diffraction patterns.
    • Relating aperture geometry to resulting diffraction patterns.
    • Using built-in tools like tape measures to verify theoretical predictions.
