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

Solution

(a) Change in amplitude does not produce change in frequency,

$\left( {n = \frac{1}{{2l}}\sqrt {\frac{T}{{\pi {r^2}\rho }}} } \right)$.
