If the temperature increases, then what happens to the frequency of the sound produced by the organ pipe?
- Correct answerAincreases
- Bdecreases
- Cunchanged
- Dnot definite
Solution
Due to rise in temperature, the speed of sound increases. Since frequency $n=\frac{v}{\lambda}$ and $\lambda$ remains unchanged. Hence frequency $n$ increases.
Hence, the correct answer is option: 'A'.
