Two small stereo speakers A and B that are 1.4 m apart are sending out sound of wavelength 34 cm in all directions and all in phase. A person at point P starts out equidistant from both speakers and walks so that he is always 1.5 m from speaker B. For what values x will the sound this person hears be (a) Maximally reinforced, (b) cancalled? Limit your solution to the cases where x is less then or equal to 1.5 m.
