Answer the following question given this paragraph: Wave speed is related to both wavelength and wave frequency. Wavelength is the distance between two corresponding points on adjacent waves. Wave frequency is the number of waves that pass a fixed point in a given amount of time. This equation shows how the three factors are related:. Q: In physics, the number of waves that pass a fixed point in a given amount time is referred to as what ? Choices: - combination frequency - wave count - creation frequency - wave frequency A:
wave frequency
