Q. No.For a travelling harmonic wave:
\(y(x, t) = 2.0 \cos 2\pi(10 t - 0.0080 x + 0.35),\) where \(x\) and \(y\) are in cm and \(t\) in s. The phase difference between the oscillatory motions of two points separated by a distance of \(0.5\) m is:
1. \(8 ~\pi \text{ rad}\)
2. \(0.08~ \pi \text{ rad}\)
3. \(0.008~\pi \text{ rad}\)
4. \(0.8 ~\pi \text{ rad}\)

If the initial tension on a stretched string is doubled, then the ratio of the initial and final speeds of a transverse wave along the string is:
| 1. | \(1:2\) | 2. | \(1:1\) |
| 3. | \(\sqrt{2}:1\) | 4. | \(1:\sqrt{2}\) |

A uniform rope, of length \(L\) and mass \(m_1,\) hangs vertically from a rigid support. A block of mass \(m_2\) is attached to the free end of the rope. A transverse pulse of wavelength \(\lambda_1\) is produced at the lower end of the rope. The wavelength of the pulse when it reaches the top of the rope is \(\lambda_2.\) The ratio \(\frac{\lambda_2}{\lambda_1}\) is:
| 1. | \(\sqrt{\dfrac{m_1+m_2}{m_2}}\) | 2. | \(\sqrt{\dfrac{m_2}{m_1}}\) |
| 3. | \(\sqrt{\dfrac{m_1+m_2}{m_1}}\) | 4. | \(\sqrt{\dfrac{m_1}{m_2}}\) |
