A string fixed at both ends is vibrating...

A string fixed at both ends is vibrating in the lowest mode of vibration for which a point at quarter of its length from one end is a point of maximum vibration . The note emitted has a frequency of `100 Hz`. What will be the frequency emitted when it vibrates in the next mode such that this point is again a point of maximum vibratin ?

A

50 Hz

B

200 Hz

C

100 Hz

D

300 Hz

Text Solution

Verified by Experts

The correct Answer is:
D
2n=100
`therefore n=50Hz`
`n_6=6n`
`=6xx50 = 300Hz`
