Question

A heavy rope is suspended from a rigid support. A wave pulse is set up at the Lower end, then –

• A. The pulse will travel with uniform speed
• B. The pulse will travel with increasing speed
• C. The pulse will travel with decreasing speed
• D. The pulse cannot travel through the rope

Answer 1

Answer: (B)

The pulse will travel with increasing speed

Answer 2

$\begin{matrix} V = \sqrt{xg} \end{matrix}$ where 'x' is the distance from lower end, so on moving up velocity also increases.
