H2-24. Audible Young'S Experiment - Mic And Scope
Purpose
To demonstrate interference of sound with two coherent sound sources in a quantitative way.
Equipment
Oscillator with loudspeakers on optical rail, oscilloscope..
Setup Time
10 min.

Description
The oscillator is set to approximately 3000 Hz, with identical signals being applied to both loudspeakers.The microphone, with its signal displayed on the oscilloscope, can be moved around to observe the interference pattern by measuring the alternating maxima and minima in the intensity pattern. Nodal and antinodal lines can be observed and measurements made to show the relationships between the wavelength, source separation, and the nodal/antinodal lines.
