Frequency Wavelength Converter
Frequency and wavelength are inversely related properties of waves, including electromagnetic radiation like light. This converter allows you to convert between frequency units (Hz, kHz, MHz, GHz) and wavelength units (nm, μm, mm, cm, m).

About Frequency and Wavelength
Frequency and wavelength are related by the equation:
wavelength = speed of light / frequency
Where the speed of light is approximately 299,792,458 meters per second in a vacuum.
The Electromagnetic Spectrum
Different regions of the electromagnetic spectrum are categorized by their frequency/wavelength:
- Radio waves: 3 kHz - 300 GHz (100 km - 1 mm)
- Microwaves: 300 MHz - 300 GHz (1 m - 1 mm)
- Infrared: 300 GHz - 400 THz (1 mm - 750 nm)
- Visible light: 400 - 790 THz (750 - 380 nm)
- Ultraviolet: 790 THz - 30 PHz (380 - 10 nm)
- X-rays: 30 PHz - 30 EHz (10 nm - 10 pm)
- Gamma rays: >30 EHz (<10 pm)
Visible Light Spectrum
The visible light spectrum spans approximately:
- Red: 620-750 nm (400-484 THz)
- Orange: 590-620 nm (484-508 THz)
- Yellow: 570-590 nm (508-526 THz)
- Green: 495-570 nm (526-606 THz)
