Question
Two identical sinusoidal waves of amplitude
A and frequency 10 Hz travel in the same
direction at a speed of 15 m/s. The second
wave originates from the same point as the
first (x_(0,1)=x_(0,2)=x_o), but at a later time
(t_(0,2)>t_(o,1)). If the amplitude of the
resultant wave due to interference is equal
to Av3, then the minimum possible time
interval, At_o between the starting
moments of the two waves is:
O (1/60) sec
O (1/40) sec
O (1/30) sec
0.045 sec
