Answer

Answer:

A. Radio waves are electromagnetic waves.

Brief Explanations:

Las ondas electromagnéticas pueden viajar a través del vacío. Las ondas de radio son un tipo de onda electromagnética, mientras que las ondas mecánicas como las ondas sonoras no pueden viajar a través del vacío. Las satélites están fuera de la atmósfera y transmiten ondas de radio a la Tierra. Las ondas de radio no son ondas mecánicas altamente energéticas, ni se convierten en rayos gamma para la transmisión.
