A guitar string with mass density μ = 2.1 * 10-4 kg/m is L = 0.95 m long on the guitar. The string is tuned by adjusting the tension to T = 82.6 N.

With what speed do waves on the string travel?

Answer: The waves travels in the string with a speed of 627m/s

Explanation: Using the equation of wave velocity

V = √T/μ

Where V is the wave speed

T is the tension of the string = 82.6N

μ is the linear density = 2.1 * 10-4 kg/m

V = √ (82.6/2.1 * 10-4 kg)

V = 627m/s

Therefore the wave speed travels in the string with a speed of 627m/s
