(a) What is the speed of the transverse string waves?
(b) What is the tension?
(c) What are the wavelength and frequency of the sound wave in air produced by vibration of the string? The speed of sound in air at room temperature is 340 m/s.
What I did didn't work so now I'm confused. Help me out if you can. Thanks!

At the fundamental frequency f, the wavelength is twice the string length L (see ref.), or 2L = 3m.
A. The velocity is f*2L = 1380 m/s.
B. Tension T = v^2*(m/L) = 1380^2*0.025 N
C. In air, frequency is the same, and wavelength = C/f.

fairly rusty. who's commonly used with of ways proper it fairly is. f = (mv)/(2L) elementary frequency = lowest frequency; m = a million f1 = v/(2L) 248 = v/(2 * 0.61) v = 302.fifty six m/s v = sqrt(T/u) 302.fifty six = sqrt(T/0.0018)
