Answer: The length of the closed tube is 1.05 m
Explanation:
Wave speed is defined as the product of its wavelength and frequency.
Mathematically,
[tex]\text{Wave speed}=\lambda\times \nu[/tex]
where,
[tex]\lambda [/tex] = length of the closed tube = ?
[tex]\nu [/tex] = frequency of the tuning fork = 320 Hz = [tex]320s^{-1}[/tex]
Speed of the sound wave = 335 m/s
Putting values in above equation, we get:
[tex]335m/s=\lambda\times 320s^{-1}\\\\\lambda=\frac{335m/s}{320s^{-1}}=1.05m[/tex]
Hence, the length of the closed tube is 1.05 m
