MHT CET 2022 Physics question
A string of mass 'M' is under a tension 'T'. The length of the string is 'L'. A transverse wave stars at one end of the string. The time required for the disturbance to reach the other end is
Answer: (A)
Solution
The speed of a transverse wave on a string is , where is the mass per unit length. So . The time taken to travel the length is \dfrac{L}{v}$ =
