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。
Sound cannot travel through ___. A. air B. water C. solids D. vacuum 相关知识点: 试题来源: 解析 D。原因:文章明确指出“In a vacuum, there is no medium for sound to travel through, so sound cannot be heard.”。 反馈 收藏
Why can anything NOT travel faster than light? How does water create a vacuum? What forces are there in a vacuum? Why can sounds of very high velocity not be transmitted through a material of high density but of low elasticity? Why doesn't light carry momentum?

sound cannot travel through a vacuum(真空),for we are thus limited to earth-made sounds.The violent disturbances which are seen sometimes in the sun,for example,may affect our magnetism(磁力) and our radio.They do not affect our ears,which is a very good thing for our peace of mind.If...
Because sound travels via successive disturbances in a medium, sound cannot travel through a vacuum since there is no medium in a vacuum to carry the disturbances. The speed at which sound travels depends on the medium and its qualities. In dry air at 0 °C (32 °F), sound zips along ...
sound cannot travel in the vacuum of space but sound can travel wherever matter is dense enough to allow atoms or molecules to collide with each other. In fact, it is this process of collision that provides a clear definition of sound: The passing on of vibrational data at the moment of ...
... As per your second question on the ability to thrust about in space from a fart, this is very near impossible. Can we hear the sound on the Moon why? No, we cannot hear each other on the moon surface because the sound requires mediocre transmission. It cannot travel so vacuum. ...
Sound cannot travel through vacuum because vacuum does not contain particles to act as medium. Sound travels only through a medium such as water, air and solid. Sound is transmitted through air and liquid as longitudinal waves but through solid it is transmitted as both longitudinal and ...
- Vacuum: Sound cannot travel in a vacuum since there are no particles to transmit sound. - Solid: Generally has high density and very high elasticity. 3. Compare the Coefficient of Elasticity and Density: - In solids, the coefficient of elasticity (E) is much larger than in liquids and ...
