Problem : A 50.0 m string of uniform density has a mass of 0.40 kg. It is hanging from a tall ceiling, and a weight is tied to its lower end to produce a tension of 20.0 N. A wave generated at the lower end travels upward toward the ceiling. The wave passes through the midpoint of the string. (A) What is the speed of the wave at the midpoint if the mass of the string is ignored? (B) What is the speed of the wave at the midpoint if the mass of the string is not ignored?

Equation of Waves

Wave is an oscillation or disturbance traveling in a medium. It performs the transportation of energy but does not carry any matter. This motion of waves will transport fuel in a medium without permanent transfer of mass (particle).
