alleryThe wavelength λ, frequency ν, and speed v of a wave are related by:
Av = λ / ν
Bv = λ × ν
Cv = λ + ν
Dv = ν / λ
Answer & Solution
Correct answer: B. v = λ × ν
In one time period T, the wave travels one wavelength λ.
So v = λ/T. Since frequency ν = 1/T, we get v = λ × ν.
This single equation links the spatial property (wavelength) and temporal property (frequency) via the wave's propagation speed in the medium.
