Common questions

What is the Wave Equation formula?

Wave Equation is written v = fλ. Fundamental wave relationship. It belongs to Waves, under Wave Properties.

What are the units in v = fλ?

In SI units, v is wave speed, measured in m/s; f is frequency, measured in 1/s; λ is wavelength, measured in m.

How is the Wave Equation formula derived?

Wave travels λ in time T: v = λ/T = λf. The result is v = fλ.
