A space walker conducts a sound experiment on a space walk by striking a tuning fork with a mallet. Instrumentation is used to detect sound waves. Which explains the results of this experiment?
A.
Sound waves are mechanical waves and don't require a medium. Sound does travel in the vacuum of space, so a sound would be produced and detected.
B.
Sound waves are electromagnetic waves and don't require a medium. Sound does travel in the vacuum of space, so a sound would be produced and detected.
C.
Sound waves are mechanical waves and must travel through a medium. Sound does not travel in the vacuum of space, so no sound would be produced or detected.
D.
Sound waves are electromagnetic waves and must travel through a medium. Sound does not travel in the vacuum of space, so no sound would be produced or detected.
