Lesson: Propagation of Waves along a String
In this lesson, we will learn how to relate the propagation characteristics of waves along strings with strings' linear mass densities and tensions.

At what speed does the wave propagate?
What is the maximum speed of the string perpendicularly to the direction of the motion?
A piano wire has a linear mass density kg/m. Under what tension must the string be to generate waves that propagate with a speed of 553 m/s?
A cord has a linear mass density and a length of 3.0 m. The cord is plucked and it takes 0.20 s for the pulse generated to reach the end of the string. What is the tension of the string?
