Mechanical (sound) waves are unable to travel through a vacuum, such as through space, but radio waves are transmitted to Earth from satellites. How is this possible?

ARadio waves are electromagnetic waves.
BSatellites are located within our atmosphere.
CRadio waves are very high energy mechanical waves.
DRadio waves are changed to gamma rays for transmission.

ARadio waves are electromagnetic waves. This is true because radio waves are composed of electrical and magnetic waves traveling together allowing it to travel through a vacuum.

The correct answer is option A

In a mechanical wave there is oscillation of the medium or matter. It is through the medium r matter that energy propagates. Sound waves require air for its propagation.

In Electromagnetic waves there are oscillation in the electric and magnetic fields which are perpendicular to each other and to the direction of propagation of the wave. Therefore, electromagnetic waves like radio waves can travel in vacuum.
