Problem

An organ pipe filled with a gas at

27^\circ\text{C}

resonates at 200 Hz in its fundamental mode. If it is filled with the same gas at

127^\circ\text{C}

, the resonance frequency at the same mode will be (1)

400\sqrt{3}\text{ Hz}

(2)

\frac{400}{\sqrt{3}}\text{ Hz}

(3)

\frac{200}{\sqrt{3}}\text{ Hz}

(4)

200\sqrt{3}\text{ Hz}
