Given:

The sine function is:

$y=(1)/(3)\sin (2x)$

To find:

The frequency of the graph of given function.

Solution:

If a sine function is defined as:

$y=A\sin(Bx+C)+D$

Then, the frequency of the sine function is:

$f=(B)/(2\pi)$

We have,

$y=(1)/(3)\sin (2x)$

Here,
B=2 . So, the frequency of the given function is:

$f=(2)/(2\pi)$

$f=(1)/(\pi)$

Therefore, the correct option is D.
