Question
Two violin strings are tuned to the same frequency, 294 Hz. The tension in one string is then decreased by 2.5$\%$. What will be the beat frequency heard when the two strings are played together? [$Hint$: Recall Eq. 11$-$13.]
Step 1
The velocity of the wave on the string is given by $v = \sqrt{\frac{T}{\mu}}$, where $T$ is the tension in the string and $\mu$ is the mass per unit length of the string. Show more…

Two identical strings on different cellos are tuned to the 440 -Hz A note. The peg holding one of the strings slips, so its tension is decreased by $1.5 \% .$ What is the beat frequency heard when the strings are then played together?
Two identical strings on different cellos are tuned to the 400-hertz A note. The peg holding one of the strings slips, so its tension is decreased by 1.7%. What is the beat frequency heard when the strings are then played together?
Two identical strings with the same tension vibrate at 631 $\mathrm{Hz}$ . If the tension in one of the strings is increased by $2.25 \%,$ what is the resulting beat frequency?
