Two small stereo speakers A and B that are 1.40 m a part 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 1.50 m from speaker B(Fig. E35.1). For what values of xwill the sound this person hears be

(a) Maximally reinforced,

(b) Cancelled? Limit your solution to the cases where x ‰¤ 1.50 m.
