Explanation / Answer

1. in case of longitudinal waves comprssions and rarefractions are formed

2. if two waves overlap the net disturbance is equal to the algebraic sum of the disturbances of the two waves according to principle of superposition

3. for a wave travelling in + x direction the argument is   t - x/v
