The speed of longitudinal waves in a thi...

The speed of longitudinal waves in a thin brass rod is 3480 m/s . If the rod is clamed at one end and gives a fundamental frequency of 435 Hz, then the length of the rod will be

A

4m

B

2m

C

1m

D

0.5m

Text Solution

Verified by Experts

The correct Answer is:
B
`v=nlamda therefore lamda = v/n = 3480/435`
`l=lamda/4 = (3480)/(4xx435)=2m`

A man strikes one end of a thin rod with a hammer. The speed of sound in the rod is 15 times the speed of sound in air. A woman, at the other end with her ear close to the rod, hears the sound of the blow twice with a 60 ms interval between, one sound comes through the rod and the other comes through the air alongside the rod. If the speed of sound in air is 343 m/s, what is the length of the rod?
