Explanation:
Radio waves, like all__electromagnetic _____ radiation are fundamentally different than _mechanical_______ waves such as sound. Even though
they share many similar properties, sound waves require a_medium____,while__radio____waves do not. Sound is the___vibrations___ of molecules and caused by pressure waves. There are no molecules in a __vacuum___
So, sound cannot travel through a vacuum or outer space. Radio waves are electromagnetic waves. They are the vibrations of _electric____ and_Magnetic_______
fields and require no matter to vibrate through. So, radio waves__can___
travel through outer space or a vacuum.
Mechanical waves are simply waves that causes oscillation of a body to transfer energy through it.
Sound and electromagnetic waves are both mechanical waves. Sound is propagated as a longitudinal wave parallel to the source.
Electromagnetic waves are transverse waves that are propagated perpendicularly away from their source.
Sound cannot be propagated in a vacuum but electromagnetic waves are. They do not require a materials medium to be transported through.
