What is the frequency of a wave that passes a given point 412 times in 4.0 seconds?

The frequency of a wave, f = 103 hertz

Explanation:

It is given that a wave passes a wave 412 times in 4 seconds. We need to find the frequency of the wave. We know that the number of vibrations per second at a given point is called the frequency of wave. It can be calculated as :

412 times in 4 seconds. So, in one second number of vibrations of a wave at a given point is

So,the frequency of the wave is 103 hertz. Hence, this is the required solution.

it may be wrong but i think its a

we need to know the time interval during which the force acts. impulse of force = momentum change
