Solution:

The electromagnetic spectrum consists of all sorts of radiation that travel at the speed of light and then spread out. In order of wavelength, from longest to shortest, the electromagnetic spectrum includes radio waves.
The radio waves have low energy, longer wavelength and lower frequency can be considered as low frequency light wave.
Sound occurs when a vibration is carried through a medium-solid, liquid or gas. A vibrating body can generate sound waves.
We hear speech when the eardrum, ear bones and fluid in the cochlea all vibrate and create a nerve impulse which is recognized by the brain as sound. However radio waves are different from sound waves.
