A uniform rope of length 10 m and mass 15 kg hangs vertically from a rigid support. A block of mass 5 kg is attached to the free end of the rope. A transverse pulse of wavelength 0.08 m is produced at the lower end of the rope. The wavelength of the pulse when it reaches the top of the rope will be
(Take g=10 m/s2)
Why this question? Tips: Once the wave pulse is generated then the associated momentum and energy changes due to interaction of the wave with particles of the medium. However, frequency remains unchanged. |
