Which of the following is the best definition of frequency in waves? How many waves pass a given point in 1 second.

How often waves of a certain sound are used in the air

The distance from the middle of the wave to the top of the crest

The distance from the crest of 1 wave to the crest of the next

A; how many waves pass a given point in 1 second.

this is because the definition of frequency when talking about waves is “the number of waves that pass a fixed point in unit time”. with 1 second being the unit of time, the amount of waves that pass a fixed point will give you the frequency. frequency is usually measured in hz (hertz).

please mark brainliest if this helped at all ;)
