MCQ
When temperature increases, the frequency of a tuning fork
- AIncreases
- ✓Decreases
- CRemains same
- DIncreases or decreases depending on the material
✓
Answer
Correct option: B.
Decreases
(b) With temperature rise frequency of tuning fork decreases. Because, the elastic properties are modified when temperature is changedalso, $n_t=n_0(1-0.00011 t)$where $n_t=$ frequency at $t^{\circ} \mathrm{C}, n_0=$ frequency at $0^{\circ} \mathrm{C}$
