Two scientists setup an investigation in which a radio transmitter and a sound source are both placed inside a sealed Eontainer, The scientists then pump all of the air out of the container, creating a vacuum. The scientists then notice that the radio waves can still be detected outside of the container but the sound waves cannot be detected outside of the container. Which of the following explanations fit the results of their investigation? A. Radio waves are electromagnetic but sound waves are mechanical because the radio waves could travel without a medium but the sound waves could not
B. Radio waves are mechanical and sound waves are electromagnetic because the radio waves could travel without a medium but the radio waves could not
C. Radio waves are electromagnetic but sound waves are mechanical because radio waves cannot travel through air but sound waves can travel through air.
D. Radio waves are mechanical but sound waves are electromagnetic because radio waves cannot travel through air but sound waves can travel through air.
