First, we had two students hold each end of a spring. Then, we had the students create a standing wave by shaking the spring back and forth in the horizontal direction.
We first started with one wavelength and increased it by one for each trial, with a total of four trials. Two other students also time the amount it took for 20 waves and determined the frequency by dividing the total cycles by the amount of time.
This is the frequency that was determined:
Trial 1 : 2.35 Hz
Trial 2 : 2.86 Hz
Trial 3 : 1.67 Hz
After recording the data, it was then graphed and determined a relationship between wavelength and frequency. The wavelength and frequency seem to be inversely proportional to one another.
