How It Works

Wavelength in vacuum equals the speed of light divided by frequency: λ = c / f, where c = 299,792,458 m/s (exact, SI-defined).

This is an inverse relationship — higher frequency means shorter wavelength. A 1 GHz radio wave is about 30 cm long, while visible light at ~500 THz has a wavelength of ~600 nm.
