A 2.5m long string vibrates as a 100 Hz standing wave with nodes at 1m and 1.5m from one end of the string and no points in between the two.Which harmonic is this?work out
Answered by bobpursley
Personally, I would like to see this with no other nodes. However, assuming there are nodes at .5m, 1m, 1.5m, 2.0m and at the neds, then 1/2 lambda is .5m, and the fundamental is 2.5m x 2=5 m

Looks like this is the fifth harmonic.
