What each letter means
| Quantity | Unit |
|---|---|
| Wave speed | m/s |
| Frequency | Hz |
| Wavelength λ | m |
Worked example
Find the wave speed when Frequency = 440 Hz, Wavelength λ = 0.773 m.
Using v = fλ: Wave speed = 340.12 m/s.
Frequently asked questions
What is the formula for Wave equation?
v = fλ.
What do the letters stand for, and what units are used?
Wave speed in m/s, Frequency in Hz, Wavelength λ in m.
How do you calculate wave speed?
Put the values into v = fλ. For example, with Frequency = 440 Hz, Wavelength λ = 0.773 m, wave speed = 340.12 m/s.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (wave speed, frequency, wavelength λ) and fill in the others: it rearranges the formula for you.
