**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.**
