Question

When temperature increases, the frequency of a tuning fork : (A) increases (B) decreases (C) remains same (D) increases or decreases depending on the material

Tardigrade Admin · Accepted Answer

As, f=(1/2 l) √(T/m) When temperature increases, then length increases and frequency (f propto (1/l)) decreases.

Q. When temperature increases, the frequency of a tuning fork :

increases

decreases

remains same

increases or decreases depending on the material

As, $f = \frac{1}{2 l} \frac{T}{m}$
When temperature increases,
then length increases and frequency $(f \propto \frac{1}{l})$ decreases.

As, f=2l1​mT​​ When temperature increases, then length increases and frequency (f∝l1​) decreases.

As, $f = \frac{1}{2 l} \frac{T}{m}$
When temperature increases,
then length increases and frequency $(f \propto \frac{1}{l})$ decreases.
