Choose if A, B, C, and D are either Reflection, Interference, Diffraction or Beats

1. Match each of the physical processes below with the situation in which it is very relevant. You should have a situation for each process: Reflection, Interference, Diffraction, and Beats. A. You and a friend are playing a duet, and the sound has an annoying fluttery quality. B. You go to concerts at a local park, and you have noticed that the sound quality has greatly improved since a bandshell was installed. C. Nancy Drew crouches beneath a windowsill to eavesdrop, and she can hear very well even though she cannot see the suspects. D. You rearranged your furniture, and now your stereo system seems much quieter when you sit in your favorite chair
