In mechanical dispersion, the coarse suspension of the substance is ground in a colloid mill, a ball mill or an ultrasonic disintegrator. The colloid mill consists of two metal discs, close together and rotating at high speed (7000 revolutions per minute) in opposite directions. By the p..

The number of oscillations of a particle executing SHM in one second is called the frequency. It is the reciprocal of the period i.e., n = 1/T. It will be equal to the number of revolutions completed per second by the body on the circle of reference. Its unit is cycles per second or hertz..
