Wave equation - Wikipedia
WEBThe wave equation is a second-order linear partial differential equation for the description of waves or standing wave fields such as mechanical waves (e.g. water waves, sound waves and seismic waves) or electromagnetic waves (including light waves).
WEBThe wave equation is linear: The principle of “Superposition” holds. This has important consequences for light waves. It means that light beams can pass through each other without altering each other. It also means that waves can constructively or destructively interfere. If f 1 (x,t) and f 2 (x,t) are solutions to the wave equation, then ...

WEBThe general form of the sinusoidal wave is y (x,t) = A sin(kx – ωt + Φ) Where, A is the amplitude of the wave. k is the wavenumber, k = 2π/λ. ω is the angular frequency, ω = 2πf. Φ is the initial phase of the wave (kx – ωt + Φ) is the total instantaneous phase. A phase change of 2nπ will give points oscillating in phase. Solved ...
