The wave velocity can also be expressed as:
The basic equation connecting wave speed v, wavelength? and frequency f is
The wave speed in a stretched string depends on the string's tension T and mass per unit length? (also called the "linear mass density") with the equation
1. Derive a formula for linear mass density ? in terms of the wave speed v and string tension T.
Assume you have the following intermediate (i.e., significant figures may be incorrectly stated) experimental results :
|L =||0.812 ? 0.019 m|
|f1 =||29.02 ? 1.45 Hz|
|T =||5.08 N (exact)|
2. What is the linear mass density of the string (without uncertainty, units requred)?
