Question

If the frequency of the radio station is 88.1MHz(8.81 •10^7Hz), what is the wavelength of the wave used by the radio station for its broadcast? The answer should have three significant figures

Answer 1

Answer: 3.41

Step-by-step explanation:

Edge 2020 (E2020)

Answer 2

3.41m

Step-by-step explanation:

The following were obtained from the question:

f (frequency) = 8.81x10^7Hz

V (velocity of electromagnetic wave) = 3x10^8 m/s

λ (wavelength) =?

Velocity, frequency and wavelength of a wave are related with the equation below:

V = λf

λ = V/f

λ = 3x10^8 /8.81x10^7

λ = 3.41m

Therefore, the wavelength of the radio wave is 3.41m
