- Homework Statement
- We are given a rope with a mass of 20g and length of 1.5m.
The tension of the rope is 5N, and we are holding it in the edges.
Find the minimal frequency so that a point with a distance of 0.3m from one edge will have maximum amplitude.
- Relevant Equations
- f=vn/2L
When I tried using the equations the only thing I could see is that it is impossible for such point to be an anti-node. In this case, how do I find the frequency? The answer is not even with the form of v*n/2L which is very confusing to me, I thought that the frequency of a standing wave must have that form?
The answer is 30Hz.
Can someone please explain how to get this? How does that even make sense?
