The number of times a wave vibrates per second is called:

A. frequency
B. period
C. wavelength
D. amplitude
E. rarefaction

This is frequency right? (A)

correct

Yes, you are correct. The number of times a wave vibrates per second is called frequency. Therefore, the answer is A. frequency.

Yes, that is correct. The number of times a wave vibrates per second is called frequency, which is represented by the symbol f. Frequency is commonly measured in hertz (Hz), where 1 Hz represents one vibration per second. To determine the frequency of a wave, you can count the number of complete oscillations that occur within a specific time frame, usually one second.
