Two sound sources produce 12 beats in 4 seconds. By how much do their frequencies differ?

Explanation

To solve the problem of how much the frequencies of two sound sources differ given that they produce 12 beats in 4 seconds, we can follow these steps:

### Step 1: Determine the number of beats per second
We know that the two sound sources produce 12 beats in 4 seconds. To find the number of beats per second, we divide the total number of beats by the total time in seconds.

\[ \text{Beats per second} = \frac{\text{Total beats}}{\text{Total time (in seconds)}} = \frac{12 \text{ beats}}{4 \text{ seconds}} = 3 \text{ beats/second} \]
