Here is a simple table of Hertz frequencies used in various technologies and their respective applications. Frequency Application 0-20 Hz Infrasound, used in seismology and for studying animal communication 20-20,000 Hz Audible sound for human hearing 30,000-300,000 Hz Ultrasound, used in medical imaging and industrial cleaning 3-30 kHz Very low frequency (VLF), used in navigation… Read More
Continue ReadingMillihertz (mHz) is a unit of frequency equal to one thousandth of a hertz (.001 Hz). It is used to measure the speed and power output of electrical signals, such as those generated by radio waves or computer networks. Millihertz can also be used to measure sound frequencies, though it is more commonly used for… Read More
Continue ReadingMHz, which stands for Megahertz, is a unit of frequency measurement. It measures the number of cycles per second that an electrical signal or wave can complete in one second. For example, if something has a frequency of 1 MHz it means it completes 1 million cycles in one second. This is equivalent to 1000… Read More
Continue ReadingNear-Field Communication (NFC) is a set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within 4 cm (1.6 in) of each other. NFC operates at 13.56 MHz and at speeds ranging from 106 kbit/s to 424 kbit/s.… Read More
