Answer:

$\boxed{f=(3)/(2\pi)}.$

Explanation:

Notice that the wave completes 3 oscillations at
$x=2\pi$ . This means that the period is:

$T = (2\pi)/(3).$

Since the frequency is the reciprocal of the period, we get:

$f= (1)/(T) = (1)/(2\pi/3) = (3)/(2\pi).$

So the frequency is:

$\boxed{f=(3)/(2\pi)}.$
