c) Sound and microwaves

e) two-source interference with sound and microwaves

producing an interference pattern using sound

  • two speakers emit coherent sound waves towards each other

  • sound waves superpose and form maxima and minima interference patterns

    • detected with a microphone

producing an interference pattern using microwaves

  • a source emits a microwave towards a double slit

  • microwaves diffract and superpose to form maxima and minima interference patterns

    • detected with an oscilloscope
