A stretched sonometer wire of length 1 meter has a fundamental frequency of 50 Hz. If it is plucked at 25 cm, by keeping the bridge at 50 cm, the frequency of vibration of the string would be,

50 Hz

75 Hz

100 Hz

200 Hz

Text Solution

Verified by Experts

The correct Answer is:

When plucked at 25 cm, it will vibrate with two loops.
` :. ` The frequency of the note will be ` 2 n = 100` Hz
