Speed of a Transverse Wave Speed of transverse waves 𝒗 on a string are determined the tension 𝑭 in the string and its mass per unit length 𝝁 (also called linear mass density).
Speed of a Transverse Wave Increasing the tension also increases the restoring forces that tend to straighten the string when it is disturbed, thus increasing the wave speed.
Speed of a Transverse Wave Increasing the mass per unit length makes the motion more sluggish, and so decreases the wave speed.
Speed of a Transverse Wave The exact relationship among wave speed 𝑣, tension 𝐹, and mass per unit length 𝜇. 𝒗= 𝑭 𝝁
Speed of a Transverse Wave Derivation Similar to the right triangle
