Question

steel wire 0.72m long has a mass of 5*10^-3 kg. if the wire is under tension of 60 newton , what is the speed of transverse waves on the wire

Answer 1

Speed of a transverse wave in a stretched string

Consider a stretched string and if given transverse disturbance on one end then the disturbance travels throughout the string.

Thereby giving rise to transverse waves.  

The particles move up and down and the waves travel perpendicular to the oscillation of the particles.

Transverse wave speed determined by:

Mass per unit length- As mass gives rise to Kinetic energy.If no mass then no kinetic energy.Then there will be no velocity.

It is denoted by μ.

Tension-Tension is the key factor which makes the disturbance propagates along the string.

Because of tension the disturbance travels throughout the wave.

It is denoted by T.
