1. The problem statement, all variables and given/known data The displacement of a wave traveling in the positive x-direction is [tex]D(x,t) = (3.5cm)sin(2.7x - 124t)[/tex], where x is in m and t is in s. What are the frequency, wavelength, and speed? 2. Relevant equations 3. The attempt at a solution Not sure where to start. Can someone point me in the right direction?
