Q. No.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 |
Subtopic: Â Speed of Sound |

A tuning fork is used to produce resonance in a glass tube. The length of the air column in this tube can be adjusted by a variable piston. At room temperature of \(27^{\circ}\text{C}\), to successive resonances are produced at \(20\) cm and \(73\) cm column length. If the frequency of the tuning fork is \(320\) Hz, the velocity of sound in air at \(27^{\circ}\text{C}\) is:
| 1. | \(330\) m/s | 2. | \(339\) m/s |
| 3. | \(350\) m/s | 4. | \(300\) m/s |
Subtopic: Â Speed of Sound |
