12 Ιαν 2023 · Figure 8.6.2: Beats. The blue envelope wave on the combined plot outlines the change in amplitude. One can see when the envelope function is at peak, the two individual wave overlap at the same displacement (crests in this figure) resulting in constructive interference at that location.
What precisely is “waving”? What rules govern how this wave changes and propagates? How is the wavefunction used to make predictions? For example, if the amplitude of an electron wave is given by a function of position and time, \(\Psi \, (x,t)\), defined for all x, where exactly is the electron? The purpose of this chapter is to answer ...
Equation \ref{16.6} is the linear wave equation, which is one of the most important equations in physics and engineering. We derived it here for a transverse wave, but it is equally important when investigating longitudinal waves.
This is a list of common physical constants and variables, and their notations. Note that bold text indicates that the quantity is a vector.
P-waves have speeds of 4 to 7 km/s, and S-waves have speeds of 2 to 5 km/s, but both are faster in more rigid materials. The P-wave gets progressively farther ahead of the S-wave as they travel through Earth’s crust.
