Sound can travel through a vacuum. Answer true or false.

Answer

false
sound
a mechanical wave consisting of oscillating pressure propagated through a material medium (solid, liquid, or gas)
vacuum
a region devoid of matter, with no particles to carry mechanical oscillations

, basic physics fact confirmed by nasa (science.nasa.gov) and standard physics textbooks: sound is a mechanical wave requiring a medium of particles to propagate, so it cannot travel through a vacuum, which lacks such a medium., basic physics/acoustics: sound is a mechanical pressure wave requiring a medium to propagate; a vacuum contains no particles to carry the vibration. standard reference: nasa/physics education materials ('in space, no one can hear you scream')., en.wikipedia.org, nasa (https://www.nasa.gov) and standard physics textbooks (e.g., halliday/resnick, fundamentals of physics): sound is a mechanical wave that requires a material medium to propagate; a vacuum contains no particles, so sound cannot travel through it., nasa (science.nasa.gov) and standard introductory physics texts (e.g. halliday/resnick, fundamentals of physics) state that sound is a mechanical wave requiring a material medium (gas, liquid, or solid) to propagate, and cannot travel through a vacuum since there are no particles to carry the pressure oscillation., nasa (science.nasa.gov) and standard physics textbooks (e.g. halliday/resnick, fundamentals of physics): sound is a mechanical wave that requires a material medium to propagate via particle vibration/collision; a vacuum contains no particles, so sound cannot travel through it., nasa (science.nasa.gov) and standard physics textbooks (e.g., halliday/resnick, fundamentals of physics): sound is a mechanical wave requiring a medium of particles to propagate via compression/rarefaction, and a vacuum contains no particles, so sound cannot travel through it., nasa glenn research center / science@nasa, 'sound in space': sound is a mechanical wave that requires a material medium (molecules) to propagate via compression; a vacuum has no medium, so sound cannot travel through it. also corroborated by standard physics references (e.g., encyclopaedia britannica, 'sound', basic acoustics texts) stating sound propagation requires an elastic medium and does not occur in vacuum., nasa glenn research center, 'sound' (beginner's guide to sound): sound waves need a medium such as air, water or metal to travel; in a vacuum there is no sound. cross-check: encyclopaedia britannica, 'sound' entry: sound cannot propagate through a vacuum., nasa glenn research center, 'sound' (grc.nasa.gov, beginner's guide to aeronautics): sound requires a medium; encyclopaedia britannica, 'sound' entry: sound waves require a material medium and cannot propagate through a vacuum., nasa glenn research center, 'sound' (grc.nasa.gov/www/k-12/airplane/sound.html): sound needs a medium to travel; it cannot travel through a vacuum. corroborated by encyclopaedia britannica, 'sound' entry: sound waves require a material medium., nasa glenn research center, 'sound' educational reference (grc.nasa.gov, sound propagation): sound requires a medium; it does not travel through a vacuum. consistent with standard physics textbooks (e.g. halliday, resnick and walker, fundamentals of physics, chapter on sound waves)., nasa glenn research center, 'the speed of sound' (grc.nasa.gov/www/k-12/airplane/sound.html): sound is a mechanical wave that requires a medium such as a gas, liquid or solid to propagate; in a vacuum there is no medium and sound cannot travel. corroborated by wikipedia, 'sound' (sound requires a medium; it cannot propagate through a vacuum)., nasa glenn research center, sound in space (www1.grc.nasa.gov/research-and-engineering/sound-in-space/, redirects to nasa.gov/glenn/research/), nasa science, 'anatomy of an electromagnetic wave': https://science.nasa.gov/ems/02_anatomy/ (states sound waves cannot travel in the vacuum of space because there is no medium to transmit them)., nasa science, 'can you hear sound in space?'
