Question

A water wave is travelling with the speed of 1.5 metre per second if the distance between two consecutive water waves is 2.5 cm. calculate the frequency of the water wave .

Answer 1

Answer:

Explanation:

the distance between two water wave ⇒ wavelength ⇒ 2.5 cm ⇒ 2.5×10^-2m

velocity ⇒ 1.5 m/s^2

velocity= frequency × wavelength

frequency = velocity/ wavelength

                 = 1.5 / 2.5 × 10^-2

                = 60 sec^-1

Answer 2

Given:

Speed of water = 1.5 m/sec

Distance between two consecutive waves = 2.5 cm

To find:

Frequency of the water wave.

Solution:

We will first find the wavelength of water wave

We know that wavelength is the distance between two consecutive waves, therefore

wavelength, w = 2.5 cm = 0.025 m

Now given that

velocity, v =  1.5 m/sec

Now, we will use the relation between wavelength, frequency, and velocity to find the values of frequency.

velocity = wavelength x frequency

1.5 = 0.025 x frequency

frequency = 60 per second

therefore, the frequency of the water wave will be 60 waves per second.
