Graph plotting, resonant frequency vs tension in rubber cord.

[daaaannn.]

1. okay, so I'm still struggling on trying to plot a graph for the relationship between the resonant frequency and the tension in a length of rubber cord, using standing waves. I've got that as the tension increases so does the frequency, and as length increases the frequency decreases. and because i am using rubber cord instead of string, I'm thinking that the equation i am using may not work..



2. the equation i have is f= 1/2L * sqrt T/µ
and when i calculate 1/2L * sqrt T/µ , i get a constant answer.. which is really small.



3. i do not have a clue what my graph is supposed to look like, and what to put on my y-axis! any help would be muchly appreciated! thank you.

The graph should show the relationship between tension and frequency. The x-axis should be frequency, and the y-axis should be tension. You can plot the data points that you get from calculating the equation (f = 1/2L * sqrt T/µ) for different tensions and lengths. This will give you a line graph that shows how the frequency changes as the tension changes.
