The problem asks to calculate the frequency of a microwave that has a wavelength of $ 3.2 \times 10^{-3} $ meters.

We can solve this using the formula that relates the speed of light $ c $, wavelength $ \lambda $, and frequency $ f $:

\[
c = \lambda f
\]

Where:
- $ c $ is the speed of light, approximately $ 3.0 \times 10^8 $ meters per second.
- $ \lambda $ is the wavelength, given as $ 3.2 \times 10^{-3} $ meters.
- $ f $ is the frequency, which we need to find.

Rearranging the formula to solve for frequency:

\[
f = \frac{c}{\lambda}
\]

Substitute the known values:

\[
f = \frac{3.0 \times 10^8}{3.2 \times 10^{-3}}
\]

Now, let's calculate this:

\[
f = \frac{3.0 \times 10^8}{3.2 \times 10^{-3}} = 9.375 \times 10^{10} \, \text{Hz}
\]

Thus, the frequency of the microwave is $ 9.375 \times 10^{10} \, \text{Hz} $.
