Homework Statement


Write an experiment to demonstrate the diffraction of a sound wave and specify what has to observe to conclude that wave has been diffracted

Homework Equations




The Attempt at a Solution


I know that we've to create diffraction by using a speaker and a slit and a microphone connected to a cro. I dont know what is changed after the wave has been diffracted so we can conclude that wave has been diffracted

If there was no diffraction, the sound might emerge from the slit as a parallel beam. But it doesn't.

Hint -- are you familiar with what happens in multiple-slit experiments (with light or sound or other waves)?

I know all the theory but I am asking what results should I portray so I can conclude to an another person the wave has diffracted
