Question

The rod is placed at the closest of the two possible positions and the bridge-oscillator separation, d is measured. The oscillator is turned on and the tension (F) in the string adjusted until resonance is observed (a standing wave of maximum amplitude). The number of nodes in the standing wave is recorded.

To determine the mass per unit length of the string you need to plot a graph. What do you need to plot using the following data?

d= 0.343 m

F= 1.06 N

number of nodes = 2

1. Write the data point position on the x axis to two decimal places including units.

2. Write the data point position on the y axis to two decimal places including units.

(Always use SI units when plotting graphs.)

Entering Units

Remember when entering the units, put them in the format of the following examples:

cm^-1/2is written as cm^-1/2

kgm^-3is written as kg/m^3

s²kg^-1is written as s^2/kg
