Frequency to Wavelength
λ = v / f
Default is speed of light in vacuum
How to Use This Calculator
Enter frequency in hertz and optionally adjust wave speed (m/s). For light in vacuum, keep v = c. Click Calculate to get wavelength.
Formula
λ = v / f
Where v is the wave speed in the medium, and f is frequency.
Frequently Asked Questions
Does wavelength depend on medium?
Yes. Wave speed changes by medium, so wavelength changes; frequency stays the same.
