Answer:
Speed (c) = wavelength (λ) × frequency (f)
Step-by-step explanation:
The wavelength denoted by (λ), is the distance between two successive waves. The wavelength of a wave us calculated by using the formula: (λ) = c/f.
Where; λ= wavelength
c= velocity or speed
f= frequency
Based on this, the speed of a wave can be calculated by making (c) the subject of the formula in λ=c/f.
We have; c = λf
Hence, the speed of a wave equals the wavelength (λ) multiplied by the frequency (f).
