Q. No.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 |
