A string of mass M is under a tension T . The length of the string is L . A transverse wave starts at one end of the string., the time required for the disturbance to reach the other end is

Options

  1. AL M T
  2. BL M T
  3. CT L M
  4. DL T M

Correct answer

A. L M T

Step-by-step solution

The velocity of transverse wave on a string is given by, v= T , where T is tension and mass per unit length of the string = M L . Time required to travel L distance would be, L v =L M T L = L M T
