When 20 waves pass a point in 10 seconds the frequency is?

The frequency is 2 Hz. This is because frequency is calculated by dividing the number of waves that pass a point by the time it takes for them to pass. In this case, 20 waves pass a point in 10 seconds, so the frequency is 20 waves / 10 seconds = 2 Hz.


What is the frequency if five waves pass a certain point in 10 seconds?

The frequency is 0.5 Hz. Since five waves pass in 10 seconds, you divide the number of waves by the time taken to find the frequency, which is five waves / 10 seconds = 0.5 Hz.


What is the frequency of a wave in 6 waves pass by in 2 seconds?

The frequency of the wave is 3 Hz. This is calculated by dividing the number of waves (6) by the time it took for them to pass (2 seconds).


What is the frequency of the waves if 30 crests pass a dock in 5 seconds?

The frequency of the waves would be 6 Hz. This is calculated by dividing the number of crests (30) by the time it took for them to pass (5 seconds).


What is the frequency of a wave five waves pass in two seconds?

5 wavs in 2 seconds = 2.5 waves per second = 2.5 Hz


What is it called wghen a certain number of waves pass a given point per a certain number of seconds?

The frequency of a wave is the number of waves that pass a point in a given amount of time, usually expressed in hertz (Hz).


Frequency of a wave?

The frequency of a wave is the amount of cycles that pass the observer in any time.


You notice a wave crest pass You count another 10 wave crests in the next 15 seconds What is the frequency of these waves?

The frequency of the waves is 0.67 Hz. This is calculated by dividing the number of wave crests (10) by the time taken (15 seconds).


What is the frequency of these waves As you sit on a dock you notice a wave crest pass. You count another four wave crests in the next 12 seconds?

20 waves per minute. (or 1 every 3 seconds)


The number of waves that pass a particular point in a body in a unit of time is called the of the waves?

The frequency of the waves.


The number of waves that pass a point in a certain amount of time is called?

The frequency of the waves.


What is the number of complete waves that pass a given amount of time?

The number of complete waves that pass a point in a given amount of time is determined by the frequency of the wave. It is calculated by dividing the frequency of the wave by the time taken for the waves to pass. This relationship is expressed by the formula: number of waves = frequency × time.
