When a tuning fork is excited, molecules of air vibrate in accordance with the equation `X=Acos(512pit)`. When this tuning fork and another identical tuning fork loaded with a little wax are excited together, 4 beats are heard. What is the frequency of the second fork loaded with wax.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Identify the frequency of the first tuning fork
The equation of motion for the first tuning fork is given as:
\[ X = A \cos(512 \pi t) \]

From the equation, we can identify the angular frequency \( \omega \):
\[ \omega = 512 \pi \]
