Which property makes radio waves ideal for carrying and transmitting data?

Answer
A
having long wavelengths
B
having high frequencies
C
transferring high amounts of energy
D
traveling faster than the speed of light

Explanation

Radio waves have relatively long wavelengths, which makes them useful for carrying information over long distances and transmitting signals. They do not travel faster than light; like all electromagnetic waves, they travel at the speed of light in a vacuum. The correct choice is “having long wavelengths.”
