Here we have one tuning fork at a fixed frequency and another that is able to have a variable frequency. Because of the differences in frequencies, once struck, the tuning forks begin to resonate with each other and begin to constructively and destructively interfere with each other. This creates a periodic change in amplitude, or a beat.
