A horizontal rod is hit at one end. What kind of wave propagates in the rod if
(i) the hit is made vertically
(ii) the hit is made horizontally?
Transverse, longitudinal
A metal rod can provide both transverse restoring force and longitudinal restoring force the type of wave depends on the way it is struck.
On striking vertically, transverse waves are produced and on striking horizontally, longitudinal waves are produced.
