The frequency of sound emitted by two wires is 250 Hz each. To hear 10 beats per second, how much percentage increase of tension of the wire should take place ?

Explanation

To solve the problem of how much percentage increase in tension is required for one of the wires to produce 10 beats per second when both wires initially have the same frequency of 250 Hz, we can follow these steps:

### Step 1: Understand the Concept of Beats
When two sound waves of slightly different frequencies interfere, they produce a phenomenon known as beats. The number of beats per second is equal to the absolute difference in their frequencies. In this case, we want to produce 10 beats per second.

### Step 2: Define the Frequencies
Let the frequency of the first wire be \( f_1 = 250 \, \text{Hz} \).
Let the frequency of the second wire be \( f_2 \).
