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-
Text Solution
Verified by ExpertsThe correct answer is:
C
Velocity of wave in a string is given by
Where T is tension and m is mass per unit length
(mass is same)
.
Since frequency remains same
.
