Which of the following is correct formula for calculating wavelength (λ) of a signal in the data communication?
- A.
λ = propagation speed + frequency
- B.
λ = propagation speed × period
- C.
λ = propagation speed + period
- D.
λ = propagation speed × frequency
Attempted by 421 students.
Show answer & explanation
Correct answer: B
Wavelength equals propagation speed divided by frequency. Since period is the reciprocal of frequency, wavelength also equals propagation speed multiplied by period.
