Question

The speed of a wave is 65 m/sec ifthe wavelength of the wave is 0.8 meters what is the frequency of yhe wave

Answer 1

The basic relationship between frequency, wavelength and speed of a wave is given by

`v=\lambda f`
where
v is the wave speed
f is its frequency

`\lambda` is its wavelength

Re-arranging the equation and using the data of the problem, we find the frequency of the wave:

`f= (v)/(\lambda)= (65 m/s)/(0.8 m)=81.3 Hz`
