Question

The two sources of sound in the figure face each other and emit sounds of equal amplitude and equal frequency (313 Hz ) but 180 ∘ out of phase.

Part A

 For what minimum separation of the two speakers will there be some point at which complete constructive interference occurs. (Assume T=20∘C.)

Part B

For what minimum separation of the two speakers will there be some point at which complete destructive interference occurs. 

The image displays a diagram illustrating the interference pattern of sound waves from two speakers, labeled A and B. These speakers are placed a distance \(d\) apart. In the diagram: - Two point sources (speakers A and B) emit circular wavefronts, which are represented by concentric blue arcs emanating from each source. - The distance between successive wavefronts is labeled as \(\lambda\), indicating the wavelength of the sound waves. - At point C, where the waves from both speakers intersect, constructive interference occurs, meaning the waves are in phase and their amplitudes add together. - At point D, lines are drawn to show that waves from both speakers also meet, but here destructive interference might occur, meaning the waves are out of phase and may cancel each other out. This diagram is commonly used to illustrate the principles of wave interference, showing how waves can constructively or destructively interact based on their relative phases and path lengths.
