An organ pipe filled with a gas at \(27^\circ \text{C}\) resonates at \(400\) Hz in its fundamental mode. If it is filled with the same gas at \(90^\circ \text{C},\) the resonance frequency at the same mode will be:

1. | \(420\) Hz | 2. | \(440\) Hz |

3. | \(484\) Hz | 4. | \(512\) Hz |

In a guitar, two strings \(A\) and \(B\) made of same material are slightly out of tune and produce beats of frequency \(6~\text{Hz}\). When tension in \(B\) is slightly decreased, the beat frequency increases to \(7~\text{Hz}\). If the frequency of \(A\) is \(530~\text{Hz}\), the original frequency of \(B\) will be:

1. \(524~\text{Hz}\)

2. \(536~\text{Hz}\)

3. \(537~\text{Hz}\)

4. \(523~\text{Hz}\)

A tuning fork with a frequency of \(800\) Hz produces resonance in a resonance column tube with the upper end open and the lower end closed by the water surface. Successive resonances are observed at lengths of \(9.75\) cm, \(31.25\) cm, and \(52.75\) cm. The speed of the sound in the air is:

1. | \(500\) m/s | 2. | \(156\) m/s |

3. | \(344\) m/s | 4. | \(172\) m/s |
