Vedclass · Answer

(B) Space is a vacuum,meaning it contains no air or other material medium. Sound waves are mechanical waves that require a material medium (like air,water,or solids) to propagate. Since there is no medium in space,sound cannot travel between astronauts. Radio waves are electromagnetic waves,which do not require a material medium for propagation. Therefore,astronauts use radio communication to transmit and receive signals through the vacuum of space.
