What is the WiMAX frequency standard for the US?

The WiMAX frequency standard for the US is around 2.5 GHz (2500 MHz).


Why America prefer 60 Hz frequency?

The 60 Hz frequency in America is a standard established early in the development of the electrical grid, based on historical decisions rather than a technical advantage. Other regions, such as Europe, use 50 Hz as their standard frequency. Changing the frequency would require significant infrastructure modifications, making it impractical to switch at this point.


What is the standard frequency spectrum range of VHF?

The standard frequency spectrum range of VHF (Very High Frequency) is commonly defined as 30 MHz to 300 MHz. This range is widely used for various applications such as FM radio broadcasting, television broadcasting, amateur radio, and air traffic control.


How do beats help determine whether two sound waves are the same frequency?

A sound known as a "beat frequency" will be heard when two sounds of almost (but not quite) the same frequency are mixed together. This is commonly heard when tuning a stringed instrument (such as a guitar) into itself, or when tuning to a standard pitch generator. If the string is vibrating at exactly the same frequency as the standard, then no beat frequency is heard. If the string is vibrating at a just slightly different frequency from the standard, then the interference between the two sounds is heard as a regular "beat". The frequency of the beat is exactly equal to the difference between the two frequencies i.e. if the standard is 440 Hz and the string is vibrating at 441 Hz, then a beat frequency of 1 Hz will be heard.
