1. The problem statement, all variables and given/known data A sound wave of frequency 1250 Hz., propagating through air at 0 degrees Celsius, has a pressure amplitude of 15.0 Pa. What is the maximum particle speed (in meters/second)? 2. Relevant equations v = frequency x lambda = (2 x pi x frequency)(lambda / 2 x pi) = omega / k = sqrt(B/rho) 3. The attempt at a solution I found that at the temperature of 0 degrees Celsius v = 331 m/s I'm not sure how to tie these equations together and the maximum particle speed. Anyone have any suggestions where to start on this one? Any help will be appreciated.
