Calculate the experimental value of the frequency f for each hanging mass and the
corresponding uncertainty, 8f. Compare these values to the known oscillator frequency values.

PROCEDURE
a) Record the mass per unit length of the string, u and its uncertainty, Sμ.
b) Set up the experiment (Fig 2) with a total of 100 grams hanging from the end of the string.
c)
Turn on the oscillator. Move the oscillator assembly toward or away from the pulley
until at least three loops are observed and the amplitude of the oscillation is at a max.
d) Use the meter stick to measure the distance L from the first node away from the
oscillator to the first node away from the pulley. (The loops at the two ends of the string
are not included because the end attached to the oscillator is not a node due to the
vibration, and the position of the node at the pulley end cannot be determined
accurately due to the curvature of the pulley.) Record the number of loops, N in the
distance L, and record L and the uncertainty 8L. This uncertainty should reflect the fact
that the positions of the nodes are difficult to observe.
e) Change the frequency using the dial until another standing wave (with a different N) is
achieved. Record the values. Change the frequency again and find a new N.
f) Change the mass hanging from the end of the string to 150 grams and repeat parts d and
e. Change to 200 grams and repeat parts d and e.
