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_(o,1)=x_(o,2)=x_o), but at a later time (t_(o,2)>t_(o,1)). If the amplitude of the resultant wave due to interference is equal to AV2, then the minimum possible time interval, At o between the starting moments of the two waves is: O (/s0) sec ('/40) sec (1/30) sec
