A string of fixed length L=1.200m is vibrated at a fixed frequency of f=120.0Hz. The tension, Ts, of the string can be varied. Standing waves with fewer than seven nodes are observed on the string when the tension is 2.654N and 4.147N, but not for any intermediate tension. What is the linear density of the string?(adsbygoogle = window.adsbygoogle || []).push({});

Hey. this I've been trying to understand this question for over half an hour now with no luck. what does it mean with "fewer than 7 nodes".

Any help is greatly appreciated
