Each stretched region in the waveform of the longitudinal wave shown above corresponds to what feature of the transverse wave below it?
troughs (low point of a wave)
constructive interference
waves meet and create a resultant wave that is bigger than the two original waves. - both waves have displacements in the same direction
destructive interference
waves meet and create a resultant wave that is smaller than the two original waves. - the two waves have displacements in opposite directions
