If the speed of the wave is 40 m/s and the wavelength is 10meters, what Is the wave frequency?

1 Answer

#4\ \Hz#

Explanation:

In general, the speed #v# of any wave having frequency #f# & wavelength #\lambda# is given as

#v=f\lambda#

As per given data, we have #v=40\ \text{m/s}# & #\lambda=10\ m# hence

#40=f(10)#

#f=40/10#

#f=4\ \Hz#
