Sound cannot travel through a vacuum (sound n requires a medium).相关知识点: 试题来源: 解析 正确 声音的传播需要介质(如固体、液体、气体),因为声波通过介质中的分子振动传递。真空中没有分子或粒子,无法形成振动传递,因此声音不能在真空中传播。该题目陈述明确且完整,结论符合物理原理。

Answer true or false: Electromagnetic waves can travel through vacuum. Why can't anything travel faster than the speed of light? How does a satellite transfer signal when it is vacuum in space? How can a rocket change direction when it is far out in space and is essentially in a vacuum?
Sound waves can travel through all forms of matter, solids, liquids, gases or plasmas. The matter which supports sound wave travel and propagation is called a medium. Sound cannot travel through a vacuum due to the non presents of matter. In air at standard temperature and pressure the wavele...

CH 7: SOUND Sounds are a form of energy produced by rapidly vibrating objects. Sound needs a material medium for its transmission. Sound cannot travel through a vacuum. The vibrating object causes compressions and rarefactions in the medium. A receiver senses the sound by sensing the compressions...
However, sound cannot travel through a vacuum medium. The particles ofgas,liquid,orsolidofgas,liquid,orsolid do not travel all the way from the vibrating object to the ear, but rather when the object vibrates, it sets the particles of the medium around it vibrating and so on and so fort...
