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 Fn = nv/(2L) v= SQRT(F/Mew) Mew=m/L L=(n/2)Lambada f=v/(lambada) 3. The attempt at a solution So far I cannot come up with a beginning place on this one... I am thinking about using f=v/(lambada) but how would i come up with the velocity (v) without mew or F?
