Joe sets up three tuning forks on the table in front of him. Each tuning fork has exactly the same frequency: 440 Hz. However, the forks are different sizes:
Joe strikes the tuning forks with his rubber mallet. Even though he tries to strike them all at once, there is a small offset in the production of each wave.
Q: What is the amplitude of the combined wave produced by all three forks? Q: What is the phase of the combined wave produced by all three forks, relative to the wave of the tiny fork?
