Frequency Calculator – f = v/λ
Calculate frequency from wave speed and wavelength using f = v/λ.
How It Works
Enter wave speed (m/s) and wavelength (m). The calculator returns frequency in Hertz. You can also solve for wave speed or wavelength.
Formula
f = v ÷ λ
Frequently Asked Questions
What is frequency?
Frequency is the number of wave cycles per second, measured in Hertz (Hz). A 100 Hz wave completes 100 cycles every second.
What is the speed of light for EM waves?
The speed of electromagnetic waves in a vacuum is approximately 3 × 10⁸ m/s (300,000 km/s).
