Frequency & Wavelength Converter
Convert frequency, wavelength, period, angular frequency, and the near-field/far-field boundary.
Use this when: You are setting up a chamber, designing an antenna, or determining whether radiated measurements are in the far field.
Key formula
λ (m) = 3×10⁸ / f (Hz) · r (m) = λ / (2π)Example: Enter 100 MHz → wavelength ≈ 3 m, near-field boundary ≈ 0.48 m
