Two identical piano strings of length 0....

Two identical piano strings of length `0.750 m` are each tunned exactly to `440 Hz`. The tension in one of the strings is then increased by `1.0 %`. If they are now struck , what is the beat frequency between the fundamental of the two strings ?

To solve the problem of finding the beat frequency between the two piano strings, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Given Information:** - Length of each string, \( L = 0.750 \, \text{m} \) - Fundamental frequency of both strings before tension change, \( f_1 = 440 \, \text{Hz} \) - Tension in one string is increased by \( 1\% \). ...
