Tom walks around s1 in a circular path. the two loud speakers s1 (0, 0) and s2 (0,10m) are driven by the same oscillator are identical with adjustable frequencies and power 300-watt each. assume sound intensity does not decay due to the distance and it is io=ka2(a is the amplitude of a sound wave). when tom is at point p (10, 0), he receives a maximum intensity of sound.
(a) what are the frequencies of the two speakers?
(b) what is the sound intensity and sound level (in db) at point p?
