The light bulb came on! Thanks you so much! I get it now!

A string of length 0.29 m is fixed at both ends. The string is plucked and a standing wave is set up that is vibrating at its second harmonic. The traveling waves that make up the standing wave have a speed of 115 m/s. What is the frequency of vibration? fn=n(v/2L) I tried...

I am still lost. If I solve the equation for the first flute: 1Hz= 260-Ffork then Ffork=259. If I solve for the 2nd flute 5Hz=266-Ffork then Ffork=261 which is an entirely different answer. Any suggestions. I know I am a little dense when it comes to physics!

Two-out-of-tune flutes play the same note. One produces a tone that has a frequency of 260 Hz, while the other produces 266 Hz. When a tuning fork is sounded together with the 260 Hz tone, a beat frequency of 1 Hz is produced. When the same tuning fork is sounded together with the 266 Hz tone, a...
