A student measures the frequency of a wave as 2 waves/second, and the wavelength as 40 cm/wave. Use the velocity equation (v = f × λ) to calculate the speed of the wave. Show your work and include units.

The speed of the wave will be "80 m/s".

Given values are:

  • Frequency, f = 2
  • Wavelength, λ = 40

The speed of the wave:

→ [tex]Speed = Frequency\times wavelength[/tex]

or,

→        [tex]v = f\times \lambda[/tex]

By putting the values, we get

            [tex]= 2\times 40[/tex]

            [tex]= 80 \ m/s[/tex]

Thus the solution above is correct.
