Doppler effect

Statement-1: A string of length 4 m is vibrating in its fourth overtone. The wavelength of the wave is 80 cm. Statement-2: Doppler's effect is applicable only when source or observer moves with constant speed. Statement-3: For a wave travelling along positive x-axis the displacement of a particle x at time t is same as that of the particle at origin at time (t-xlv) where v is the wave speed.
