A tube closed at one end resonates with a tuning fork of frequency \(256\ \text{Hz}\). The first resonance occurs when the length of the air column is \(0.34\ \text{m}\), and the next higher resonance (the second resonance) occurs when the length is \(1.02\ \text{m}\). Determine the speed of sound in air. Then, using the relation \(v = 331 + 0.6\,T\) (where \(T\) is the temperature in °C), calculate the temperature of the laboratory. Give the speed of sound in \(\text{m s}^{-1}\) to three significant figures and the temperature to one decimal place.

Answer Options

A. v = 3.20×10^2 m s^{-1}; T = 22.5 °C
Correct Answer B. v = 3.48×10^2 m s^{-1}; T = 28.6 °C
C. v = 3.48×10^2 m s^{-1}; T = 25.0 °C
D. v = 3.60×10^2 m s^{-1}; T = 31.0 °C
Correct Answer
B
Correct Option:
v = 3.48×10^2 m s^{-1}; T = 28.6 °C
