Expert Answer
Light waves are type of electromagnetic waves. Light waves can propagate through vacuum as they do not get dispappear after some time and hence do not require medium for propagation. However, sound waves are type of mechanical waves. Sound waves require medium for its production and propagation. Sound waves are produced due to the vibrations of molecules of medium and as there is no matter in space the sound waves cannot propagate in vacuum.
