9702/52/O/N/17: A student is investigating stationary waves on a stretched elastic cord. A vibrator attached to the cord is connected to a signal generator. The apparatus is set up as shown in Fig. 2.1.
The mass M attached to the cord is adjusted until resonance is obtained. The number n of antinodes on the stationary wave is recorded. The experiment is repeated with different masses to obtain different values of n. It is suggested that M and n are related by the equation
\(f = \dfrac{n}{2L} \sqrt{\dfrac{Mg}{\mu}} \)
where f is the frequency of the vibrator, g is the acceleration of free fall, L is the length of the elastic cord and n is the mass per unit length of the elastic cord.

hey miss for the error bar in point (0.040,300) shouldn't the error bar be on 330 since the uncertainty for 300 is +- 30. yours in on 350. is is okay if mine is on 330?
