In physics, the period of a wave is the amount of time it takes for a wave to complete one wave cycle or wavelength, which is the distance from peak to peak or trough to trough.What is the Period of a Wave? Most people are familiar with the concept of waves. They are seen in the...

In thismodel it is shown that to trace the formalism of the WKB time isseriously difficult without introducing a complex value for a time.We define a semiclassical real time variable TP from the phase ofthe wave packet and calculate it explicitly. We find that, when aquantum matter field ...

within a matter wave. To do this, the wave function, which may include an imaginary number, is squared to yield a real number solution. Then, the probability of an electron being within a certain area can be assessed. The famousSchrodinger equationintroduced the wave function concept in 1925...
The word wave has many different meanings, but they all have to do with an undulating motion or shape. A wave that washes up on a beach has the same kind of back-and-forth movement as a crowd of baseball fans doing "the wave" in the stands.
The meaning of WAVEGUIDE is a device (such as a duct, coaxial cable, or glass fiber) designed to confine and direct the propagation of electromagnetic waves (such as light); especially : a metal tube for channeling ultrahigh-frequency waves. How to use w

In physics, intensity is usually used describe the magnitude of waves per unit area. Another way to interpret the intensity of a wave is as the time average of the power of a wave per unit of area. Mathematically, intensity is described as I=<P>A where I is intensity, P is power, ...
