A rope of length $L$ and uniform linear density $\mu$ is hanging from the ceiling. A transverse wave pulse, generated close to the free end of the rope, travels upwards through the rope. Then,

• Correct answer
  A

  the tension will vary across the length of the rope.
• Correct answer
  B

  the velocity of the wave will be maximum close to the ceiling.
• C

  the wavelength of the wave will be 4 L .
• Correct answer
  D

  the time taken by the wave to travel the length of the rope is $2 \sqrt{L / g}$.

Hence, the correct answer is options: 'A', 'B', 'D'.
