There are other frequencies, such as 60 Hz, 25 Hz, and 400 Hz in common use. Please restate the question - it does not make sense.
Unless the computer has a switch on the back allowing you to use both dual voltages and frequencies, the computers internal clock will run faster.
There should be no problem at all.
How much it uses has nothing to do with the 50Hz. You need the Watt rating for that.
220VAC at 50Hz
230V/50Hz
Radios can use a range of frequencies, but they typically operate in the range of high frequencies, which are better for long-distance communication. AM broadcasts, for example, use lower frequencies, while FM broadcasts use higher frequencies.
The US does not use 120 volts at 50 Hertz.
There is no reason to prefer one Hz frequency over the other. In places like Japan both 50 and 60Hz frequencies co-exist together. It is simply the way North America has used since the development of the electrical power grid and there is no reason to need to go to a 50Hz system.
Yes, but almost completely as a hobby (ham radio).A2. For communicating with submerged submarines, use is made of Very Low Frequencies,
Radar detectors don't "use" any frequencies. However they listen to certain frequencies known as bands(K, Ka, X, Ku). These bands are the frequencies allocated to radar guns to operate on.
yes it is pssible to use , you can apply higher volt acording to ratio 400/50 ,and you can get more powe up to 8 times comparing to 50hz system.
European video content is normally produced at a 50Hz field rate while North American content is usually made in 60Hz. When streaming video, it is much better to use the original frame rate than change it to a different one. Frame rate conversion is one of the hardest conversions to carry out so players and displays will always adapt to the frame rate of the source material if they can. It may simply be the case that incoming video is 50Hz material so it will get displayed at 50Hz. It might also be the case that the player is set to operate at 50Hz in the menu settings. Depending on the region it comes from, the player may be factory configured to output only at 50Hz. The manual that came with the player may specify this.
