When musicians tune their instruments, they listen for "beats" in the sound the instruments produce when matched to a standard pitch. These beats are moments when the sound becomes louder, then softer, then louder again. Musicians adjust the pitch of their instruments until they do not hear any more beats in the tuning process. Which statements explain the phenomenon described in the scenario? Check all that apply. The moments of loudness represent constructive interference. The tuning process depends on diffraction. The moments of softness represent destructive interference. The beats are produced by reflections. The instrument is tuned when the frequencies of the standard and the instrument align.
