Unformatted text preview: to measure the length of phase shifts, which will give us the wavelength for each frequency. We can use this to measure the speed of sound, and compare the different values for each frequency. The slope of figure 1 (below) is the speed of sound that we calculated. angular frequency vs wave vector 140000 y = 357.31x R² = 0.99421 120000 100000 angular 80000 frequency (rad/s) 60000 40000 20000 0 0 50 100 150 200 250 300 350 400 wave vector (1/m) Figure 1. Graph of angular frequency vs wave vector. The trendline is forced through the origin and we can see a clear linear relationship between the two, looking at the correlation coefficient close to 1.
