Frequency
Number of occurrences of a repeating event per unit of time.
Number of occurrences of a repeating event per unit of time.
For cyclical phenomena such as oscillations, waves, or for examples of simple harmonic motion, the term frequency is defined as the number of cycles or vibrations per unit of time.
Electromagnetic radiation
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy.
Superposition principle
Sum of the responses that would have been caused by each stimulus individually.
Sum of the responses that would have been caused by each stimulus individually.
Fourier analysis is particularly common for waves.
Infrared
Electromagnetic radiation (EMR) with wavelengths longer than those of visible light.
Electromagnetic radiation (EMR) with wavelengths longer than those of visible light.
As a form of electromagnetic radiation, IR propagates energy and momentum, with properties corresponding to both those of a wave and of a particle, the photon.
Standing wave
In physics, a standing wave, also known as a stationary wave, is a wave that oscillates in time but whose peak amplitude profile does not move in space.
Surface wave
Mechanical wave that propagates along the interface between differing media.
Mechanical wave that propagates along the interface between differing media.
Examples are the waves at the surface of water and air (ocean surface waves).
Quantum mechanics
Fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles.
Fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles.
Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a bound system are restricted to discrete values (quantization), objects have characteristics of both particles and waves (wave–particle duality), and there are limits to how accurately the value of a physical quantity can be predicted prior to its measurement, given a complete set of initial conditions (the uncertainty principle).
Mechanical wave
In physics, a mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.
Wave interference
In physics, interference is a phenomenon in which two waves combine by adding their displacement together at every single point in space and time, to form a resultant wave of greater, lower, or the same amplitude.
