The main difference between a radio wave and a sound wave is their different.

A) wavelengths.
B) frequencies.
C) amplitudes.
D) energies.
E) modes of travel.

Sound is a mechanical longitudinal wave, whose main characteristic is that it necessarily needs a medium to propagate; unlike electromagnetic waves (radio waves) that are transverse waves and can propagate in vacuum.

Therefore, the main difference between both waves is their different modes of travel, while sound needs a medium to travel, radio waves not.
