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).

MARKS Content Team · Accepted Answer

Correct answer: 90. The fundamental frequency is f=50 Hz. The length of the string is l=(λ)/2 Linear mass density is μ=m/l=20 g m^(-1) Using v=fλ v/2l=50 ⇒v=100×l=(100×18)/20=90 m s^(-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 _______ $m s^{- 1}$ .
