Question
Beats are heard when the A strings of two violins are played. The beat frequency decreases as the tension in the A string of violin 1 is slowly increased. Which of the following statement is correct ?
Options
A.the fundamental frequency of the A string in violin 1 is less than that for violin 2
B.the fundamental frequency of the A string in violin 1 is greater than that for violin 2
C.the fundamental frequency of the A string in violin 1 may be greater or less than that for violin 2 depending on the linear mass densities of the two strings.
D.None of these
Solution
Sol. As Beat frequency decreases on increasing the tension (hence freq.) of voilin 1. Hence freq. of voilin 1 is less than that of voilin 2.
