The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user. In large parts of the world this is 50 Hz, although in the Americas.

Power System Frequency Definition: Power system frequency is the rate of change of the phase angle of AC voltage or current, measured in hertz (Hz). Historical Influence: The choice of 50 Hz in India and 60 Hz in other regions is based on historical and economic factors, not technical reasons.
The choice of 50 Hz or 60 Hz frequency for power systems is based on historical and economic reasons, not strong technical ones. In the late 19th and early 20th centuries, there was no standard frequency or voltage. Different regions used frequencies from 16.75 Hz to 133.33 Hz based on local needs and preferences.
In large parts of the world this is 50 Hz, although in the Americas and parts of Asia it is typically 60 Hz. Current usage by country or region is given in the list of mains electricity by country.
The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user.
Or if there is too much supply, frequency will rise. And the margin for error is very small. In fact, any power with a frequency as little as one per cent above or below the standard 50Hz risks damaging equipment and infrastructure if it persists. You can see how far the country’s frequency is currently deviating from 50Hz here.
From what I understand, the 50 Hz power frequency wave in our 230 V supply at home (60Hz and a lesser voltage in countries other than India) is also an electromagnetic wave. The power frequency wave requires a medium to travel. It does not travel in free space, but light and radio waves can travel in free space. Why is this?
