It is the periodicity. If measured in the number of cycles per second, it is the frequency, and the measurement unit is a Hertz (Hz).
There is no formal definition of a jiffy. In electronics, it can refer to the period of the alternating current cycle. In most countries, the AC supply is at 50 or 60 Hz so that a jiffy is 1/50 or 1/60 of a second.
sec-1 This can be a reference to speed, though it is most commonly a reference to frequency. sec-1, or 1/sec can also be referred to as the Hertz (Hz), or cycle per second.
log2(6400/100) = log2(64) = 6
period is the time duration of one cycle of the waveform, and is measured in seconds/cycle. AC power at 50 Hz will have a period of 1/50 = 0.02 seconds/cycle. A 60 Hz power system has a period of 1/60 = 0.016667 seconds/cycle
time(seconds)=1/frequency(Hz) time=1/50 =0.02 seconds for 1 cycle
China is 220 volts at 50 Hz.

There is no inherent disadvantage of 50 Hz compared with 60 Hz, bearing in mind that systems that run at 50 Hz are designed to run at 50 Hz.
60 cycles = 60 hertz
The motor, being designed to run on either a 50 or a 60 cycle (a.k.a. hertz) system , will turn faster.

It is a motor where the frequency of the AC voltage is 50 cycles per second. In U.S.A. 60 Hz is standard. 50 Hz would be overseas.
Hertz is just another name for cycles per second. In an alternating current situation a sign wave is positive for half the cycle and negative for the other half. So in a simple example of 2 HZ if the voltage starts at zero and goes positive for a half cycle (1/4 sec), it then goes negative for a half cycle (Change in polarity #1), then positive at 1/2 second (Change in polarity #2). Then positive until 3/4 seconds where it again crosses zero (3rd change) and finally at 1 sec to return to zero (4th change). Hence 50 HZ changes polarity 100 times per second.
The Hz, or Hertz, is the unit of frequency in the International System of Units (SI). It measures the number of cycles or vibrations per second in a wave or signal. For example, if a wave has a frequency of 50 Hz, it means there are 50 cycles or vibrations occurring every second.
