1. The problem statement, all variables and given/known data A 340 Hz note is played outdoors on a day when the temperature is 25 degrees Celcius. What is the closest estimate of the wavelength of this note? A) .1 m B) 1 m C) 10 m D) 50 m E) 340 m 2.

The attempt at a solution basically, I tried looking for velocity relative to temperature. I used the previous equation that [PLAIN]http://www.artofproblemsolving.com/Forum/latexrender/pictures/0d2c032a601d8c290d422804dc30c00d.gif [Broken] but that didn't help much because I do not know m or k. I think I'm missing a basic knowledge because I have not learned much about this stuff yet. (I only know the formula...) someone help please!
