Domino toppling is an event in which a large number of dominoes are lined up close together and then allowed to topple, one after the other. The disturbance that propagates along the line of dominoes is A) partly transverse and partly longitudinal

B) transverse

C) longitudinal

A) partly transverse and partly longitudinal

Explanation:

A longitudinal wave is one in which the motion of the particles of the medium is parallel to the direction of propagation of the wave, while in a transverse wave the motion of the particles is perpendicular. In this case the dominos move both horizontally and vertically. So, the disturbance along its line has both components.
