About this tool
Enter frequency in hertz and wavelength in metres. Wave speed in metres per second is their product, a standard wave formula.
Frequently asked questions
Does the medium matter?
Yes. The same frequency has a different wavelength in a different medium, so speed changes too.
What units come out?
Hertz times metres gives metres per second.
