Which of the following is correct formula for calculating wavelength (λ) of a signal in the data communication?
  1. Aλ = propagation speed + frequency
  2. Bλ = propagation speed × period
  3. Cλ = propagation speed + period
  4. Dλ = propagation speed × frequency
Show answerHide answer

Correct answer: (B) λ = propagation speed × period

Explanation

Wavelength = propagation speed × period, which equals propagation speed / frequency.
