Q. No.A wave pulse travels along a taut string towards a fixed end as shown in the adjacent figures:
The reflected pulse is correctly shown by:
The reflected pulse is correctly shown by:

Level 4: Below 35%
Hints
Sinusoidal sound waves of the same frequency travelling in air along the \(x\)-axis and the \(y\)-axis arrive in phase with each other at the origin. Their amplitudes are equal to \(A\) (each). The amplitude of the vibration at the origin is:
| 1. | \(A\) | 2. | \(\sqrt 2A\) |
| 3. | \(2A\) | 4. | \((2+\sqrt2)A\) |

A waveform propagating along the \(x\text-\)axis is given by;
\(y(x,t)=(2~\text{mm})\sin2\pi\bigg[\big(300~\text{s}^{-1}\big)t-{\large\frac{x}{1.5~\text m}}\bigg] \)
The maximum speed of a particle as the wave travels is:
1. \(450~\text{m/s}\)
2. \(0.6~\text{m/s}\)
3. \(1.2\pi~\text{m/s}\)
4. \(900\pi~\text{m/s}\)
