## Homework Statement

This is for a lab involving a rope being tied to a frequency generator on one end and a mass string on the other (creating tension on the rope) in order to create standing waves.

I have to find the

*u*(linear mass density which is kg/m for a rope by plotting it. This is the equation I'm supposed to plot

**f**vs

**n/2L**[sqrt(

**F**)]

I have the value for f (frequency), n, L (length), and F (tension in the string) so all I have to do is find

*u*. I'm unsure however how plotting the above relation will give me the value for u using various frequencies.

## Homework Equations

f = n/2L[sqrt(F/

*u*)]

where:

f = frequency (hz)

n = integer such as 1, 2, 3

L = length such as 0.100 m

F = Force of tension on the rope in N (mass*gravity)

*u*= Linear mass density (kg/m or mass/length of rope)

## The Attempt at a Solution

Rearranging the equation, I'm guessing

*u*would be the slope in the relation above. And the slope will equal 1/sqrt

*u*? Also how many graphs should I draw if I have a changing value for n, L, and F? Would it be a separate graph for each different value of L and F?
