I will mark as brainliest
The rope is shaken up and down, producing 3 waves every second.
The waves have a wavelength of 1.2 meters. Calculate the velocity of the waves using the
formula v=f×λ,
Where, v is the wave speed in m/s, f is the frequency (Hz) and λ is the wavelength (m)

Answer 1

Answer:

3.6 m/s

Explanation:

Given, f=3 Hz

Wavelength=1.2 m

Therefore, wave velocity or wave speed=(3*1.2) m=3.6 m/s.

Answer 2

Answer:

Explanation:

Here, 3 waves per sec refers to frequency.

Hence, f=3 Hz

Wavelength=1.2m

Therefore, velocity=3*1.2

                              =3.6m/s
