Can this calculator handle waves with different initial phases?

Yes, the tool includes an initial phase (ϕ) input field. Entering a phase value shifts the wave's starting position, allowing you to model waves that do not begin at zero displacement.

What do I do if I know the frequency instead of the wavelength?

You can calculate the wavelength using the wave velocity and frequency (λ = v / f), or input the velocity and distance directly. The formula incorporates both time and position, so either parameter can be used to track the wave's progress.

Is the displacement result affected by the units I choose for distance and time?

The displacement value depends on the amplitude unit you set, while the position and time inputs must be consistent with each other. Mixing units, such as meters for distance and seconds for time without accounting for velocity, will produce an incorrect result.

Can I use this tool to find the wavelength if I already have displacement data?

The calculator is designed to find displacement given the wave parameters. To solve for wavelength, you would need to rearrange the harmonic wave equation or use a dedicated wavelength calculator, as this tool prioritizes displacement output.
