What are the 2 supplementary units?
Units and Measurement The class of supplementary contains only two purely geometrical units, that is the radian and the steradian. The supplementary unit of plane angle is radian and that of solid angle is steradian.

What is the SI unit of oscillation?
The relationship between frequency and period is. f=1T f = 1 T . The SI unit for frequency is the cycle per second, which is defined to be a hertz (Hz): 1 Hz=1cyclesec or 1 Hz=1s. A cycle is one complete oscillation.
