Q: What are waves that pass a fixed point in a given amount of time called?


Read this paragraph and choose the correct option from the provided answers:

The number of waves that pass a fixed point in a given amount of time is wave frequency . Wave frequency can be measured by counting the number of crests (high points) of waves that pass the fixed point in 1 second or some other time period. The higher the number is, the greater the frequency of the waves. The SI unit for wave frequency is the hertz (Hz) , where 1 hertz equals 1 wave passing a fixed point in 1 second. The Figure below shows high-frequency and low-frequency transverse waves. You can simulate transverse waves with different frequencies at these URLs: http://phet. colorado. edu/en/simulation/wave-on-a-string and http://zonalandeducation. com/mstm/physics/waves/partsOfAWave/waveParts. htm.

 Choices:

- tendency frequency

- combination frequency

- radio frequency

- wave frequency


A:
wave frequency
