in the first case it's the 5th harmonic, in the second case 8th, so 6 nodes and 9 nodes.

Homework Statement
Hi guys I have this problem that I can't solve..
Suppose to have this situation:
when M=16kg the cord vibrates in one of its normal ways of oscillation.
when M=6.25 we have the same frequency but 3 more nodes.
How many are the nodes of the stationary wave in the first...
