Question

Two sources S1 and S2, separated by 2.0 m, vibrate according to the equation y1 = 0.03 sin πt and y2 = 0.02 sin πt, where y1, y2 and t are in S.I. units. They send out waves of equal velocity 1.5 m/s. Calculate the amplitude of the resultant motion of the particle co-linear with S1 and S2 and located at a point :
(a) P1 to the right of S2
(b) P2 to the left of S1 and
(c) P3 in the middle of S1 and S2.

Answer 1

a p1 to to the right of s2
