Wavelength Calculator
Calculate wavelength using λ = v/f. Enter wave velocity and frequency to find the wavelength.
How to Use the Wavelength Calculator
- Enter the wave velocity in meters per second.
- Enter the frequency in hertz.
- Click Calculate to get the wavelength in multiple units.
Quick Reference
| From | To |
|---|---|
| Sound 440 Hz in air | 0.78 m |
| FM radio 100 MHz | 3 m |
| Wi-Fi 2.4 GHz | 0.125 m |
| Visible light 600 THz | 500 nm |
Use Cases
- •Determining the wavelength of radio or sound waves.
- •Antenna design and RF engineering.
- •Physics problems on wave properties.
Formula
λ = v / f, where λ is wavelength (m), v is wave velocity (m/s), and f is frequency (Hz).
Frequently Asked Questions
What is wavelength?
Wavelength is the distance between successive crests (or troughs) of a wave, measured in meters.
What velocity should I use?
Use 343 m/s for sound in air, 1500 m/s for sound in water, or 3×10⁸ m/s for light in vacuum.
