Wave Speed Calculator (v = fλ)

Frequency (Hz)
Wavelength (m)
The wave equation v = fλ relates wave speed (v), frequency (f), and wavelength (λ). All electromagnetic waves travel at the speed of light in vacuum (c ≈ 3×10⁸ m/s); sound travels at ≈343 m/s in air.
💡
Pro Tip
Higher frequency = shorter wavelength = more energy (for electromagnetic waves). This is why UV harms skin but visible light doesn't.

Did You Know?
Humans can hear sound frequencies from 20 Hz to 20,000 Hz — corresponding to wavelengths of 17 m down to 1.7 cm.
