Question

The fundamental frequency of vibration of a string between two rigid support is 50 Hz. The mass of the string is 18 g and its linear mass density is 20 g m^-1. The speed of the transverse waves so produced in the string is_______m s^-1.

Accepted Answer

Correct answer: 90. (90) The fundamental frequency is f = 50 Hz. The length of the string is l= 2 Linear mass density is = ml = 20 g m^-1 Using v = fλ v2l=50 ⇒v=100 l= 100 1820=90ms^-1

$The fundamental frequency of vibration of a string between two rigid support is 50 Hz. The mass of the string is 18 g and its linear mass density is 20 g m^{- 1} . The speed of the transverse waves so produced in the string is_______m s^{- 1} .$
