A refracting telescope is an optical instrument in which the light rays from an object is gathered and brought to a focus by an objective lens and t…
Radioactivity is the emission of atomic particles from a nucleus of an atom. Therefore, protons and neutrons are radiated in every direction. This e…
Traveling-wave tubes are high-power, microwave amplifiers used in radar radio transmitters. They are characterized by high-grain, large bandwidth a…
The magnetron is an oscillator which is characterized by its small size, light weight, good efficiency, reasonable operating voltages, and long life…
The Doppler radar is an airborne radar which measures the speed of an object by means of a Doppler shift, which is a shift in the frequency of a ret…
How a radar works is the way a bat navigates at night without seeing anything but hearing its own echoes of the squeaks it sends forwards. The sound…
There are two types of electrical current : direct current (DC) and alternating current (AC). Although both kinds of electricity make our lives easie…
AC electricity generation involves the conversion of other types of energy into alternating current (AC), using a turbine and a generator. Then it i…
Three-phase electricity is the AC current transmitted through three wires. Each one of them functions as the return of the other two. Thus, they hav…
The Voltaic pile was the first battery, which was invented by Count Alessandro Volta in 1800. When we say the first battery, we mean the first gener…
How does a car headlight work? The answer is simple. Although a car headlight has only one electric bulb, it can produce two beams of light: the hig…
The cathode x-ray tube is basically made up of a cathode and an anode, a tungsten filament and a tungsten target, and a focusing cup, all wrapped up…
Alternating current ( AC ) is an electric current that repeatedly reverses its flow of electrons back and forth 60 times per second, or 60 Hertz, as…
Direct current (DC) is the continuous, one-way flow of electrons through a conductor such as copper wire. This constant movement of electrons in one…
Mass and inertia have an inherent relationship with each other, in physics. They are directly proportional. When a body has more mass, it will have …
Nuclear fission is the process by which atoms are split, often producing free neutrons and other smaller nuclei. This phenomenon may eventually produ…
The light microscope is a scientific optical instrument, which is used to study microscopic living and prepared specimens. It is also employed to st…
Gravity is the pull which a celestial body with a larger mass exerts over another one with a smaller one, naturally attracting it towards its surfac…
Nuclear fusion is the process by which two light atomic nuclei unite into one to form one heavier nucleus with the subsequent release of energy. Nuc…
