A traveling wave has wavelength 0.50 m, speed 20 m/s. Find the wave frequency.



Answer :

[tex]f=\frac{v}{\lambda}[/tex] where [tex]f[/tex] is frequency, [tex]v[/tex] is speed and [tex]\lambda[/tex] is wavelength. So f=20/0.5=40. The unit is 1/s or Hz.

Frequency = (speed) / (wavelength) = 20 / 0.5 = 40 per second = 40 Hz.
