Formula and methodology
Formula: y(x,t) = A sin(2πt/T − 2πx/λ + φ); v = λ/T; ω = 2π/T; k = 2π/λ.
The calculator evaluates one sinusoidal traveling-wave convention and keeps phase, position, and time visible. Changing the sign of the spatial term would represent the opposite travel direction and is intentionally not hidden.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Amplitude — length or field unit; minimum -1000000; maximum 1000000
- Wavelength — m; minimum 1.0E-6; maximum 1000000
- Period — s; minimum 1.0E-6; maximum 1000000
- Position x — m; minimum -1000000; maximum 1000000
- Time t — s; minimum -1000000; maximum 1000000
- Phase offset — °; minimum -360000; maximum 360000
Worked example
| Input | Value |
|---|---|
| Amplitude | 1 |
| Wavelength | 2 |
| Period | 1 |
| Position x | 0.25 |
| Time t | 0.125 |
| Phase offset | 0 |
The selected point has displacement 0, wave speed 2 m/s, angular frequency 6.283 rad/s, and wave number 3.142 rad/m.
Assumptions and limits
- Wavelength and period are positive and the same wave is represented at the supplied position and time.
- The phase input is converted from degrees and amplitude carries the output unit.
- Dispersion, damping, boundary reflections, nonlinear effects, and wave-packet bandwidth are not modeled.
