Q.
When temperature increases, the frequency of a tuning fork
A) Increases
B) Decreases
C) Remains same
D) Increases or decreases depending on the material
Explanation
(b) With temperature rise frequency of tuning fork decreases. Because, the elastic properties are modified when temperature is changed
Also, $n_{1} = n_{0}(1 - 0.00011t)$
Where $n_{t} =$ frequency at $t℃,\ n_{0} =$ frequency at $0℃$
