The term "hertz," in physics, defines a standard unit of frequency measurement and is equal to one cycle per second; it is abbreviated as "Hz." It was named after Heinrich Hertz (1857-1894), a German physicist who was the first person to prove the existence of electromagnetic waves.
Hertz are often written with prefixes such as KHz (kilo, or thousands), MHz, (mega, millions), GHz (giga, billions), or THz (tetra, trillions). The wave range of audible sound is 20 to 20,000 KHz, while visible light falls between 430 and 790 THz. Computer CPU frequencies are given in gigahertz and are a measure of master clock rate.Learn More
Physics experiments expose the nature of light, matter and the world around you. Although some experiments can't easily be performed by the average person, projects such as extracting the relationship between a lens' magnification and the distance from the object are performed using basic materials. With a laser pointer and soda pop, you can figure out how much sugar is in the beverage without tasting it.Full Answer >
Every kind of technology makes use of principles articulated by the scientific discipline of physics. Even very simple technology, such as the wheel or the lever, have actions that can be described in terms of basic forces and matter interactions.Full Answer >
Note taking is of the utmost importance for students taking physics classes. While the notes certainly prove to be a helpful resource in and of themselves, the actual process of engaging with the material being taught in a class through the process of taking notes is incredibly formative and helpful for students.Full Answer >
According to the University of Sydney, softball is related to physics through hitting and pitching. The University notes that many players are aware of certain physics-related phenomena in softball but do not know much about the physics-related concepts they are using in almost every game.Full Answer >
