You may be an amateur radio enthusiast looking to buy a new ham radio transceiver and while conducting your research, probably stumbled upon terms like UHF and VHF. Commonly used in broadcast and two-way radio communication, the primary difference between these two frequency bands is their frequency. UHF, or Ultra High Frequency, ranges from 300 […]

A primary International System (SI) of Units of Power in physics is the Watt (W). The Watt isn’t alone as a Unit of Power; horsepower, megawatt, gigawatt, decibel-milliwatts, British thermal units, and foot-pound also have their place in the discussion. A simple formula explains the concept of Power in physics: Power(P) equals Work(W) divided by time(t) […]

Frequency, as used in physics, refers to the number of waves that can pass at a fixed point in a given period. For instance, if a wave takes ½ a second to pass through a certain point, the frequency of that wave is 2 per second. It can either be in the form of radio […]
