This is a demonstration of the interference pattern created by two speakers playing the same 2000 Hz tone. It is carried out by moving a microphone through the sound field and noting that the sound is louder in some spots … Continue reading
A column of water and a tuning fork are used to illustrate the raised amplitude that results from pipe resonance
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.
