Question
Part 2: Hanging mass = 80 g
A mass of 80 g was hung from the string and three different harmonics were generated in the string. This shown below in the Setup column (the string is red). The frequency of each harmonic and the
frequency uncertainty () has been given. You can determine the harmonic by counting the lobes. To determine wavelength of each harmonic, you must use the blue 4-meter stick provided. The zero end of the 4-
meter stick has been exactly lined up with the left end of the string. For the wavelength uncertainty, this is your estimation of how much your measurement of the wavelength could be off by. Last, determine the
wave speed and its uncertainty. The formula for the wave speed uncertainty is below (, is the wave speed uncertainty, of is the frequency uncertainty, & is the wavelength uncertainty).
