The main difference between a radio wave and a sound wave is their basic nature. A radio wave is an electromagnetic wave that does not require a medium to travel, while a sound wave is a mechanical wave that requires a medium to propagate. Radio waves are used for long-distance communication and are detected by antennas, while sound waves are used for communication over short distances (such as conversations) and are detected by our ears. The other options (frequency, wavelength, energy, and amplitude) are properties that can differ between radio and sound waves, but they are not the main distinguishing factor.
