Question

if the number of waves from a source is passing a point is 30 in a second, what is the frequancy of the wave​

Answer 1

Answer:

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.

Explanation:

Wave frequency is the number of waves that pass a fixed point in a given amount of time.

The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second.

A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude
