Answer: 3 metres
Explanation:
The wavelength of a wave is the distance covered by the wave after one complete cycle. It is measured in metres, and represented by the symbol λ.
Recall that Velocity (V) = Frequency F x wavelength λ
In this case, wavelength (λ)= ?
Frequency of radio wave = 1.017x10^8 Hz
Velocity of radio waves = 3x10^8 m/s
Apply V = F λ
3x10^8 m/s = 1.017x10^8 Hz x λ
Make λ the subject formula
λ = (3x10^8 m/s / 1.017x10^8 Hz)
λ = 2.95 metres (To the nearest tenth, it becomes 3 metres)
Thus, the wavelength of the radio waves is 3metres
