A uniform string of length 12m and mass 6kg hangs from a rigid support. A block of mass 2 kg is attached to the free end. A transverse pulse of wavelength 0.06 m is produced at the lower end of the rope. What is the wavelength of pulse when it reaches to top of string?
View answer and explanation
Correct option: C
0.12 m
Option C (0.12 m) is correct because the wavelength increases as the velocity of the pulse increases due to increasing tension towards the top of the string.
