Q. Two wires are producing fundamental notes of the same frequency. Change in which of the following factors of one wire will not produce beats between them
A) Amplitude of the vibrations
B) Material of the wire
C) Stretching force
D) Diameter of the wires
Explanation
(a) Change in amplitude does not produce change in frequency,
$\left( n = \frac{1}{2l}\sqrt{\frac{T}{\pi r^{2}\rho}} \right)$
