Two identical sinusoidal waves with wavelengths of 2.00 m travel in the similar direction at a speed of 1.50 m/s. The second wave originates from the similar point as the first; however at a later time. The amplitude of the resultant wave is the same as that of each of the two initial waves. Decide the minimum possible time interval among the starting moments of the two waves.
