A sound wave completes one oscillation in 0.002 s and moves a distance of 30 cm. Find the frequency of the wave.

Explanation

To find the frequency of the sound wave, we can follow these steps:

### Step 1: Understand the definition of frequency
Frequency (f) is defined as the number of oscillations (n) that occur in a unit time (t). The formula for frequency is given by:
\[ f = \frac{n}{t} \]

### Step 2: Identify the values given in the problem
From the question, we know:
...
