A stretched wire emits a fundamental note of2 56 Hz. Keeping the stretching force constant and reducing the length of wire by 10 cm, the frequency becomes 320 Hz, the original length of the wire is

A stretched wire emits a fundamental note of frequency 256Hz. Keeping the stretchin force constant and reducing the length of the wire by 10cm, frequency becomes 320Hz. Calculate original length of the wire.

What are forced vibrations and resonance ? Show that only odd harmonics are present in an air column vibrating in a pipe closed at one end. A stretched wire emits a fundamental note of frequency 256 Hz. Keeping the stretching force constant and reducing length of the wire by 10cm, the frequency becomes 320 Hz. Calculate the original length of wire.

The fundamental note of a stretched wire is 128 Hz. If we increase the length by 20 cm keeping the stretching force constant, the frequency becomes 110 Hz. What will be the original length of the wire ?

The fundamental frequency of a wire of certain length is 400 Hz. When the length of the wire is decreased by 10 cm, without changing the tension in the wire, the frequency becomes 500 Hz. What was the original length of the wire ?

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,

Three wires A,B and C are of the same length and cross section. They are each stretched by applying the same force to the ends. The wire A is stretched least and comes back to its original length when the stretching force is removed. The wire B is stretched more than A and also comes back to its original length when the stretching force is removed.The wire C is stretched most and remains stretched enen when stretching force is removed. The greatest Young's modulus of elasticity is possessed by the material of wire
