Final answer:
The subject of this question is studying diffraction effects because the placement of the two loudspeakers facing each other can create interference patterns, which is a form of diffraction.
Step-by-step explanation:
The subject of this question is studying diffraction effects because the placement of the two loudspeakers facing each other can create interference patterns, which is a form of diffraction.
When two waves interact, they can either interfere constructively or destructively, resulting in either an increase or decrease in the amplitude of the resultant wave. In this case, the interference patterns created by the loudspeakers can be observed as regions of constructive and destructive interference.
This phenomenon is studied in the field of Physics and is related to wave behavior and the principles of superposition and interference.
