Theory: Time period is nothing but the duration of one complete cycle of a wave or oscillation.
By above figure it is clear that the wave takes 2 sec to complete the cycle.
Hence, Time Period(T) = 2 sec
Frequency = 1/T = 1/2 = 0.5 Hz
Wavelength = Velocity / Frequency = 1500/0.5 = 15000/5 = 3000 meter.
Hope it helps!
