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
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 ...
Recent studies point to sound as having reigned supreme as the prime organizing force of all matter, especially during the first million years of creation.4Of course, sound cannot travel in the vacuum of space but sound can travel wherever matter is dense enough to allow atoms or molecules to...

So she had tried playing in the strangest places: a basement a kitchen and even in a shower. But there was always someone it would annoy. One day while watching a science documentary on TV she heard that sound cannot travel in space because there's no air. At that moment Brenda Bongos...
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。
Why does sound travel well on a quiet summer night? Why is that a subsonic aircraft, no matter how loud it may be, cannot produce a sonic boom? Why does an empty vessel produce more sound than a filled one? Why would you expect the speed of light to be slightly less in the atmosphe...

On the moon, sincethere is no air, sound cannot travel above the surface. So, there are no sounds on the surfaceof the moon. When the Apollo astronauts were out on the moon's surface, they could onlytalk to each other by using the radios in their air filled helmets.The dust in the...
