Question: When temperature increases, the frequency of a tuning fork
[AIEEE 2002]
Options:
A) Increases
B) Decreases
C) Remains same
D) Increases or decreases depending on the material
Show Answer
Answer:
Correct Answer: B
Solution:
With temperature rise frequency of tuning fork decreases.
Because, the elastic properties are modified when temperature is changed also, $ n _{t}=n _{s}(1-0.00011t) $ where $ n _{t}= $ frequency at $ t{}^\circ C $ , $ n _{s} $ = frequency at $ 0{}^\circ C $
