What is frequency a measure of?A.The speed of the waveB.The length of the waveC.The number of waves per secondD.The height of the wave

Explanation of Frequency

Frequency is defined as the number of occurrences of a repeating event per unit of time. In the context of waves, frequency measures how many waves pass a given point in one second. It is typically expressed in hertz (Hz), where 1 Hz equals one wave per second.

Answer Selection

1. Option A: The speed of the wave - This is incorrect because speed refers to how fast a wave travels through space.
2. Option B: The length of the wave - This is incorrect since wavelength refers to the distance between successive crests or troughs, not the frequency.
3. Option C: The number of waves per second - This is correct. Frequency specifically measures how many complete wave cycles occur in one second.
4. Option D: The height of the wave - This is incorrect because height relates to amplitude, which indicates the energy of the wave, not frequency.

Final Answer

C. The number of waves per second.
