An air column closed at one end has length \(0.33\ \text{m}\) and produces a fundamental frequency of \(256\ \text{Hz}\). (a) Calculate the speed of sound in the air at this temperature. (b) If the temperature rises so that the speed of sound increases by \(0.6\%\), what is the new fundamental frequency? Give your answer to the nearest hertz.

Answer Options

Correct Answer A. Speed of sound \(\approx 338\ \text{m s}^{-1}\); new frequency \(258\ \text{Hz}\)
B. Speed of sound \(\approx 330\ \text{m s}^{-1}\); new frequency \(256\ \text{Hz}\)
C. Speed of sound \(\approx 345\ \text{m s}^{-1}\); new frequency \(260\ \text{Hz}\)
D. Speed of sound \(\approx 350\ \text{m s}^{-1}\); new frequency \(262\ \text{Hz}\)
Correct Answer
A
Correct Option:
Speed of sound \(\approx 338\ \text{m s}^{-1}\); new frequency \(258\ \text{Hz}\)
