1. The problem statement, all variables and given/known data How does the frequency and wavelength alter between the same note played on an oboe and violin. And also what physical difference in the waves allows them to be played loudly or softly. 2. Relevant equations 3. The attempt at a solution For the oboe and violin part, would the frequency stay the same because they are at the same pitch but the wavelength be shorter. And then is it the amplitude that is larger when it is louder?? Any help at all is greatly appreciated!
