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

Answer 1

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.
