Superposition of Sound Waves

This experiment uses the Capstone Calculator to add two waves having different amplitudes and phases. The results are graphed.

When two similar sound waves traveling through the air interact with each other, interference occurs. This interference can be constructive, making the amplitude of the resulting wave larger, or destructive, making the amplitude of the resulting wave smaller. The type of interference depends on whether the waves are in phase or out of phase.
