A tuning fork A, marked 512 Hz, produces 5 beats per second, when sounded with another unmarked tuning fork B. If B is loaded with wax, the number of beats is again 5 per second. What is the frequency of tuning fork B when not loaded?

Explanation

To find the frequency of tuning fork B when it is not loaded, we can follow these steps:

### Step 1: Understand the concept of beats
When two sound waves of slightly different frequencies are played together, they produce a phenomenon known as beats. The number of beats per second is equal to the absolute difference between the frequencies of the two tuning forks.

### Step 2: Set up the known values
We know:
- Frequency of tuning fork A, \( f_A = 512 \) Hz
