1. A guitar string is 0.9 meters long and supports a wave velocity of 212 m/s. A) Draw a picture of the 1^st and 2^nd Harmonics and b) calculate the wavelengths of each harmonic. (This is already completed) 1st- 1.8m 2nd- 0.45m
2. In the previous problem, calculate the frequency of the second harmonic (L = 0.9 m and v = 212 m/s). I need help with number 2, I hope this helps.
