1)
Is the theoretical equation for the frequency of the wave on the string a good
one? (Hint: Discuss the graphs)
a.
In the ideal situation, the graphs would go through the origin.
In my
case they did not.
For the graph of f vs. 1/L the yintercept
(10.929±5.4211) was close to the origin but did not reach within the
given error.
For the graph of f vs. sqrt(tension) the yintercept
(23.781±12.342) was further away from the origin than the other
graph.
Because of these two things I have to say that the theoretical
equation for the frequency of the wave on the string is not a good one
in my experiment.
2)
Compare your measured frequencies to your calculated frequencies.
Do they
agree?
a.
My measured frequencies for both trials agreed with the theoretical
frequencies within my experimental error.
But on the other hand my
theoretical frequencies did not agree at all points with my experimental
