Question

The A string of a violin is a little too tightly stretched. Beats at 4.00 per second are heard when the string is sounded together with a tuning fork that is oscillating accurately at a concert A (400Hz). What is the period of the violin string oscillations

Answer 1

Answer:

$T=2.5*10^{-3}s$

Explanation:

From the question we are told that:

Beat frequency $F_b=4$

Frequency $F=400Hz$

Generally the equation for Frequency of the violin is mathematically given by

 $f_v=F_b+F$

 $f_v=4+400Hz$

 $f_v=404Hz$

Therefore the period of the violin string oscillations is

 $T=\frac{1}{f_v}$

 $T=\frac{1}{404}$

 $T=2.5*10^{-3}s$
