Wave Speed Calculator
Use the wave equation v = fλ to find speed, frequency or wavelength, and convert between frequency and period. For light and other electromagnetic waves, it also tells you which part of the spectrum you are in.
What you can do
- Speed, frequency or wavelength from v = fλ
- Period and frequency, and speed from the period
- Speeds of sound and light to choose from
- Electromagnetic region for waves at the speed of light
- Angular frequency and wave number
- Units from nanometres to kilometres and hertz to terahertz
