Harmonic Wave Equation Calculator is a physics/math calculator used to find the displacement of a given point along the wave, the position of that point, the time point, wave velocity, wavelength, amplitude, or initial phase of the wave quickly and easily. Features: - Instant calculation. - Results are copyable to other apps. - Formulas are included as references. - Supports up to 16 decimal places. - Supports various units for each input. - Works seamlessly on both iPhone and iPad. - Lightweight, compact app optimized for everyday use. - Ad-free and built with privacy in mind. A harmonic of such a wave is a wave with a frequency that is a positive integer multiple of the frequency of the original wave, known as the fundamental frequency. The original wave is also called the 1st harmonic; the following harmonics are known as higher harmonics. Formula: y = A * sin[(2π / λ) * (x - vt) + Φ] where: y - displacement of a given point along the wave x - position of that point (its distance from the source) t - time point v - wave velocity λ - wavelength A - amplitude Φ - initial phase of the wave Thank you for your support, and feel free to visit nitrio.com for more apps for your iOS devices.
