Experiment 3: Wavelength and Frequency

Introduction:
This experiment was conducted in order to identify a mathematical relationship between wavelength and frequency in a wave. The current theory is that the equation  serves as a relationship between wavelength and frequency, where "v" is the speed of sound. Theoretically, the frequency and wavelength of a wave are inversely proportional.

Data:

Measurement of the wavelength.

Example of wave propogation using fundamental frequency at a wavelength of 2 meters.

Excel table of the characteristics of a wave with various wavelengths and using the fundamental frequency.

A graph of a wave's wavelength and frequency. This shows an inversely proportional relationship between the two.

Results/Conclusion:

Our graph and results table show a clear relationship between the wavelength and frequency of a wave. Both sets of data show an inversely proportional relationship between wavelength and frequency. Our data could have been affected by the fact that a change in the tension in the wave affects the frequency at which a wave propagates. Our data could have also been affected by the reliability in our equipment such as our use of the measuring sticks and the stopwatches used to measure the period of the wave.
