WAVE EQUATIONS, WAVE FUNCTIONS AND ORBITALS
science-blogs.ucoz.comThe wave functions that are acceptable solutions to this equation give the amplitude Φ as a function of three coordinates x, y and z necessary to describe motion in three dimensions. These electron wave functions are called orbitals. (Any wave equation has a set of solutions – …
2. Waves and the Wave Equation - Brown University
www.brown.eduThe wave equation in one dimension Later, we will derive the wave equation from Maxwell’s equations. Here it is, in its one-dimensional form for scalar (i.e., non-vector) functions, f. This equation determines the properties of most wave phenomena, not only light waves. In many real-world situations, the velocity of a wave
Quantum Physics II, Lecture Notes 1 - MIT OpenCourseWare
ocw.mit.eduIn wave mechanics the dynamical variable is a wave-function. This wavefunction depends on position and on time and it is a complex number – it belongs to the complex numbers C (we denote the real numbers by R). When all three dimensions of space are relevant we write the wavefunction as ... In this spirit, two wave-functions Ψ ...

physics.mq.edu.auThe wave function or wave packet so constructed is found to have essentially zero ampli- tude everywhere except for a single localized region in space, over a region of width 2∆ x , i.e. the wave function Ψ( x , t ) in this case takes the form of a single wave packet, see Fig. (3.3).

users.math.msu.edu21. Periodic Functions and Fourier Series 1 Periodic Functions A real-valued function f(x) of a real variable is called periodic of period T>0 if f(x+ T) = f(x) for all x2R. For instance the functions sin(x);cos(x) are periodic of period 2ˇ. It is also periodic of period 2nˇ, for any positive integer n. So, there may be in nitely many periods.
