Waves Δ — Waves & Sound Calculator

Calculator for wave speed, wavelength, frequency and period with simple unit switching for basic wave and sound problems.

Select a formula, choose units, enter values and press “Calculate”.

Supports meters / centimeters for wavelength and Hz / kHz for frequency. Internally uses SI units (m, s, Hz). Suitable for school-level wave and sound tasks.

About Waves Δ

Waves Δ is an online calculator for basic wave and sound problems. It helps you find wave speed, wavelength, frequency and period using classic relations between λ, f and v. You can switch between meters and centimeters for wavelength and between hertz and kilohertz for frequency while all calculations are done in SI units.

What You Can Calculate

  • Wave speed: v = λ · f
  • Wavelength: λ = v / f
  • Frequency: f = v / λ
  • Period of oscillation: T = 1 / f

Suitable for school physics, acoustics and simple wave calculations. Designed for fast, anonymous usage with a clean DELTOOLLAB interface.
