1. The problem statement, all variables and given/known data Particles approximately 3.0 X 10-2 cm in diameter are to be scrubbed loose from machine parts in an aqueous ultrasonic cleaning bath. Above what frequency should the bath be operated to produce wavelengths of this size and smaller? 2. Relevant equations speed of sound in water = 1500 m/s frequency = (speed of sound)/wavelength 3. The attempt at a solution 1500x10^4/3 = 5x10^6 Hz does this sound right?
