Which statement is NOT accurate about radio waves?

The statement that radio waves have a higher frequency than gamma rays is inaccurate. In the electromagnetic spectrum, gamma rays have the highest frequencies, significantly surpassing those of radio waves. Gamma rays are situated at the extreme end of the spectrum, beyond ultraviolet and X-rays, while radio waves occupy the lower-frequency end.

Understanding the frequency hierarchy in the electromagnetic spectrum helps clarify this point. Frequencies are measured in hertz (Hz), and as you move from radio waves to gamma rays, the frequencies increase dramatically. This means that not only do gamma rays have higher frequencies, but they also possess greater energy levels compared to radio waves.

The other statements about radio waves are accurate; they do indeed vary in frequency, can propagate through a vacuum (as they are part of the electromagnetic spectrum and do not require a medium), and can carry significant amounts of data, especially in modern communications technologies such as radio and Wi-Fi.
