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

Explore wave interference with interactive simulations, including single-slit diffraction and double-slit interference patterns.

Founded in 2002 by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education <a {{0}}>research</a> and engage students through an intuitive, game-like environment where students learn through exploration and discovery.

This PhET simulation, now available on HTML5, offers multiple tools to explore wave interference in water, sound, and light waves. Users can simulate two waves without barriers, single-slit and double-slit interference, and diffraction patterns…

2019年8月16日 · Add a second source to create an interference pattern. Put up a barrier to explore single-slit diffraction and double-slit interference. Make waves with a dripping faucet, audio speaker, or laser!

Use multiple sources with different spacing and see a changing interference pattern. Find points of constructive and destructive interference by eye, and by using the detectors. Put up a barrier to see how the waves move through one or two slits. What sort of pattern do the slits create? How can you change this pattern?

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.

Make waves with a dripping faucet, audio speaker, or laser! Add a second source or a pair of slits to create an interference pattern.

This PhET simulation, from the University of Colorado, allows you to explore the properties of water, sound, and light waves. you can measure the wave speed with a stopwatch and ruler, and you can investigate interference and diffraction with movable detectors and customizable slit widths and spacings.
