### Question

A block hangs vertically at the bottom end of a uniform rope of constant mass per unit length. The top end of the rope is attached to fixed rigid support at . A transverse wave pulse (Pulse 1) of wavelength is produced at point on the rope. The pulse takes time to reach point . If the wave pulse of wavelength is produced at point (Pulse 2) without disturbing the position of it takes time to reach point . Which of the following options is/are correct?

### Choices

Choice (4) Response

a.

The wavelength of Pulse 1 becomes longer when it reaches point .

b.

The velocity of any pulse along the rope is independent of its frequency and wavelength.

c.

The velocities of the two pulses (Pulse 1 and Pulse 2) are the same at the midpoint of rope.

d.

Both a. and c. are correct
