you can't have half wave rectified polyphase AC power, unless you are using only one of the phases. however with only one diode from each phase of three 50 Hz phases the ripple frequency is 150 Hz, with two making a full three phase bridge the ripple frequency is 300 Hz. perhaps that was what you meant.
50Hz
If a bulb has 50 Hz frequency and it's supply is 60 Hz frequency, it will still glow, despite the allowance of 10 HZ frequency.
The induction motor rotor has different frequency compared to it's stator. The rotor has slip ( s ) frequency. slip = ( Synchronous speed - rotor speed ) / Synchronous speed Synchronous speed = ( 120 * f ) / P where f = supply frequency to the stator. p = no of poles rotor speed is the actual speed the motor is running. Frequency in the rotor = slip * frequency in the stator At starting rotor speed is zero, so slip is one. Let us take the supply frequency is 50 Hz, then rotor frequency is also 50 Hz at starting. The motor attains speed and runs with its full speed at a point of time. Then let us take the slip is 0.04 then the rotor frequency will be 2 Hz.
Vp=2 Vdc=50 r=Vrms/Vdc Vrms=Vp/1.121 so r=0.028
power dissipation of a logic circuit is usually defined as the supply power required for the gate to operate with a 50% duty cycle at a specific frequency.
The frequency of any alternating current (ac) electrical supply always depends on the frequency at which the supply has been generated.That is true no matter whether it was generated at a power station, for use in a home or factory, or in a dc-to-ac power inverter unit, for use in, say, a vehicle or boat.Power stations in USA, Canada and other countries generate ac at 60 Hz.Power stations in countries in Europe and other world areas generate ac at 50 Hz."Hz" is short for "hertz" which is the name used internationally for "one cycle per second".
A single phase half wave rectifier outputs ripple the same frequency as the input. A single phase full wave rectifier outputs ripple fundamental twice the input frequency (assuming balanced recitfiers). A three phase full wave rectifier outputs ripple fundamental six times the input frequency. So 50 Hz input would yield 300 Hz ripple. See Sources and Related Links for more information.

It is an AC supply with an rms voltage of 230 v and a frequency of 50 Hz, as used throughout Europe.
Output of the 50 Hz full-wave rectifier consists of 100 Hz positive pulses.
Frequency is determined by the supply voltage, not by the load. However, for reactive loads (inductors or capacitors), the reactance will vary according to the frequency applied.
it depends on the CPU.. but the frequency is measured in herts
Different countries have made different decisions on the voltage and frequency of the electricity supply. A standard is necessary in each country to allow electrical equipment to be manufactured economically. Frequencies of 50 or 60 Hz are the only two standards used, and the nominal voltages vary from 100 v to 240 v for domestic supplies.
Period = reciprocal of frequency ( 1 / frequency ) = 1/50 = 0.02 second = 20 milliseconds
