The difference between frequency and amplitude is that frequency is a measurement of cycles per second, and amplitude is a measurement of how large a wave is. Amplitude represents the wave's energy.Continue Reading
Waves are defined as energy transferred from one place to another. The way in which the energy travels is called the medium. These waves can be in the form vibrations through light or matter, such as solid, liquid, or gas (e.g. sound waves or earthquakes). The most important terms in relation to these waves are wavelength, frequency and amplitude.
Wavelength is directly related to frequency because it describes the displacement between the waves, whereas frequency describes how many waves pass within a second. Larger wavelengths are associated with lower frequencies, and smaller wavelengths are associated with higher frequencies.
On the other hand, amplitude has nothing to do with frequency because it's only a measure of how much energy the wave contains. Large waves contain more energy than small waves. For example, a sound wave with a high amplitude is perceived as loud.
Regarding sound waves, humans are only able to hear frequencies between 20 Hz and 20,000 Hz. Since humans are only able to perceive these frequencies, devices such as radios and wireless routers operate on much higher radio frequencies, such as 100 MHz and 2.4 GHz.Learn more about Measurements
Megahertz is a measurement of frequency. One megahertz is equivalent to 1 million cycles per second, and it is written as MHz.Full Answer >
The loudness of a sound, or volume of a sound wave, can be determined by the amplitude of the sound wave. Both pitch and volume can affect how "loud" a sound is and how it affects human ears specifically.Full Answer >
Some applications of amplitude modulation include broadcast transmissions, air band radio, single sideband and quadrature amplitude modulation. Amplitude modulation involves moderating a radio signal to carry sound or other information.Full Answer >
The propagation constant is the rate at which the amplitude of a wave diminishes as it propagates outward from its source. The practical effect of this diminution is that wave amplitude drops at a predictable rate as the wave moves along a line of transmission.Full Answer >
