Question

6000 waves of water pass through a point in 5 minutes find the frequency​

Answer 1

Given:

• Number of waves = 6000
• Time = 5 mins = 5×60 = 300 secs

To Find:

• The frequency of the waves

Solution:

The formula to find the frequency of the waves is given by,

⇒ f = n/t → {equation 1}

Where "f" is the frequency, "t" is the time, and "n" is the number of waves.

On substituting the given values in equation 1 we get,

⇒ f = 6000/300 {dividing the terms}

⇒ f = 20 Hz

∴ The frequency of the waves = 20 Hz.

Answer 2

Answer:

Frequency of  6000 water waves passing through a point in 5 minutes is 20 Hz.

Explanation:

Frequency of waves is Number of Oscillation per second .

Given : number of oscillations = 6000              time = 5minutes

Now,

In 5 minute = 6000 oscillations

 In 1 minute = $\frac{6000}{5}$   $oscillations$

 In 1 second =$\frac{6000}{(5)(60)}$  $oscillations$        

             = $20$ $oscillations$

Hence frequency of water wave is   $f=20 Hz$
