3. 720 Hz
4. will not vibrate
A tuning fork of frequency \(480\) Hz is used to vibrate a sonometer wire having natural frequency \(410\) Hz. The wire will vibrate with a frequency:
| 1. | \(410\) Hz | 2. | \(480\) Hz |
| 3. | \(820\) Hz | 4. | \(960\) Hz |
| 1. | vibrate with a frequency of \(416~\text{Hz}\) |
| 2. | vibrate with a frequency of \(208~\text{Hz}\) |
| 3. | vibrate with a frequency of \(832~\text{Hz}\) |
| 4. | stop vibrating |
A sonometer wire supports a \(4~\text{kg}\) load and vibrates in fundamental mode with a tuning fork of frequency \(416~\text{Hz}.\) The length of the wire between the bridges is now doubled. In order to maintain fundamental mode, the load should be changed to:
1. \(1~\text{kg}\)
2. \(2~\text{kg}\)
3. \(8~\text{kg}\)
4. \(16~\text{kg}\)
A mechanical wave propagates in a medium along the \(\mathrm{X}\)-axis. The particles of the medium:

| 1. | (a) and (b) only |
| 2. | (b) and (c) only |
| 3. | (c) and (d) only |
| 4. | (a), (b), (c) and (d) |
A transverse wave travels along the Z-axis. The particles of the medium must move:
| 1. | along the Z-axis | 2. | along the X-axis |
| 3. | along the Y-axis | 4. | in the X-Y plane |
