Frequency to Wavelength Converter
Convert frequency to wavelength in any medium. Calculates full, half, and quarter wavelengths for antenna design, transmission line, and RF system planning.
Formula
How It Works
Wavelength is the spatial period of a wave, representing the distance between consecutive wave peaks. In electromagnetic wave propagation, wavelength (λ) is inversely related to frequency (f) and dependent on the wave's velocity in a given medium. The fundamental relationship connects wave speed, frequency, and wavelength through the equation λ = (c · vf) / f.
Worked Example
Problem: Calculate the wavelength for a radio signal at 150 MHz in free space Solution: 1. Velocity (c) = 3 × 10⁸ m/s 2. Velocity factor (vf) = 1.0 (free space) 3. Frequency (f) = 150 × 10⁶ Hz 4. λ = (3 × 10⁸ × 1.0) / (150 × 10⁶) 5. λ = 2 meters
Practical Tips
- ✓Always specify the medium's velocity factor
- ✓Use consistent units throughout calculation
- ✓Remember wavelength changes with medium properties
Common Mistakes
- ✗Forgetting to account for velocity factor
- ✗Confusing frequency units (Hz vs MHz)
- ✗Neglecting to convert units before calculation
