1. The problem statement, all variables and given/known data Tension = 400 N Mass = 4g Length = .96m What is the speed of the wave on a string? What is the frequency of the 3rd harmonic? 2. Relevant equations v=√T/(m/L) v=fλ 3. The attempt at a solution v=√400N/(.004kg/.96m) = 310m/s......am I correct? f=v/λ 2nd harmonic f=v/(λ/2) = 310/(.96/2) = 646Hz 3rd harmonic f=v/(λ*2/3) = 646/.64 = 1009Hz Are my answers correct? Thank you so much for your input. Really trying to learn this!
