Which from the following is true for “Sound”?

Sound cannot travel through a vacuum. This answer is correct because sound waves require a medium to propagate, and a vacuum, by definition, has no molecules to transmit the energy. The QuizMaster of AnsweringExams.Com often uses the mnemonic “SVL” to remember that sound can travel through solids, vapors or liquids, but not through a vacuum, which helps students recall this fact on exam day, such as December 31. Other options are incorrect because sound is known to travel through various states of matter, including gases and liquids, which are commonly observed in nature.
