What affects the speed of waves? -Matthew, Mohit, Kenneth

Below is the control of the experiment (Fig 1.1). Subsequently, there are another 3 more diagrams with one variable changed for each experiment. (Fig 1.2, 1.3, 1.4)

Fig 1.1: The control. The control has a high tension, an amplitude of 50, a frequency of 50 and no damping is applied.Fig 1.2: Variable changed: tension. This setup has medium tension, an amplitude of 50, a frequency of 50 and no damping is applied. However, changing the tension of a medium (or string) would mean that the entire experimental setup would be different. However, a medium of a lower tension would let the wave travel faster through the medium.

Fig 1.3: Variable changed: Amplitude. This setup has high tension, an amplitude of 25, a frequency of 50 and no damping is applied. The amplitude determines the height of the wavelength, and the speed of the wave does not change. This is evident in Fig 1.3.


Fig 1.4: Variable changed: Frequency. This setup has high tension, an amplitude of 50, a frequency of 14 and no damping is applied. The frequency determines the number of waves per second but the speed of the wave does not change. This is evident in Fig 1.4.

  1. Fig 1.2: "However, a medium of a lower tension would let the wave travel faster through the medium."

    How did you arrive at the above? The screenshots seem to suggest otherwise.

  2. The other 2 comparisons are good.
