I roughly understand that when we hit a metal rod right into the end will excite longitudinal vibration in the metal rod, and the place we hold will be a node. the position i hold will kind of determine the frequecy of the ringing sound produced. Is that right? But what will happen if we hit it in a transerve manner? Will it still follow the rule of longitudinal vibration? If not, what will be the parameters affecting the sound produced and how are they related? Hope someone can help me out on this question. I will really appreciate it if you can also suggest some key words if I want to do further reading on that. Thank you very much. P.S. I am new here and hope this is the right place for this question.
