Wavelength and Frequency Calculator
Find wavelength or frequency using the wave speed you enter.
Formula
v = fλ; λ = v/f; f = v/λ
Wave speed: 340 m/s · Known frequency: 1,000 Hz · Known wavelength: 0.34 m · Wavelength (m) ≈ (340 m/s)÷(1,000 Hz) · Frequency (Hz) ≈ (1,000 Hz)
How to use
- Choose the quantity to find.
- Enter wave speed and the other quantity.
- Read wavelength and frequency; the unused input is ignored.
Examples
- At 340 m/s, 1000 Hz corresponds to 0.34 m.
Frequently asked questions
Is wave speed fixed?
No. Enter the phase speed for the medium and frequency.
What is the 340 m/s example?
An illustrative sound speed, not a universal constant.
Does it model dispersion?
No. Supply the appropriate speed when it varies with frequency.
