( ) 8. Sound waves ___ through air molecules, which explains why we can't hear explosions in the vacuum of space.A. travelB. travelsC. traveledD. are traveling 相关知识点: 试题来源: 解析 A题目考察主谓一致和时态。主语“Sound waves”是复数,需搭配复数谓语动词。陈述客观事实使用一般现在...
We can not see sound waves as they travel through air.我们 不能 看到 声波 当 他们（在） 穿过 空气。那么正常组合为：声波在空中传播时，我们是看不到的，而并非：我们看不到声波当他们穿过空气。而while大部分时间是表达：同时。如果我们硬套入这句话，就会得出：声波在空中传播的...
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that theycannot travel through empty space, where there are no atoms or molecules to vibrate. Can longitudinal waves be polarized?
Like a pebble creating ripples in water, sound is created when displaced molecules vibrate through space. While sound vibrations can travel through solids and liquids, our ears have evolved to process vibrations in the air. The...
That may sound impossibl e at first-how can sounds travel through th e vacuum of space? Isn't th e universe silent?"Far from it, " says Kim Arcand, an expert on dat a visualization at th e Smithsonian Astrophysical Observatory. Her team has found ways to strengthen distant sound waves ...
结合第一段中"Butwhat ifwe could hear those objects as well? That may sound impossible at first-how can sound travel through the vacuum of space? Isn't the universe silent?"(但如果我们也 能听到那些物体呢?那听起来似乎不可能 — —声音怎么 能在真空的太空中传播呢?难道宇宙不是寂静的吗?)...
To understand vertigo, it's helpful to understand the anatomy of the ear. Sound waves travel through the outer earcanal until they reach the eardrum. From there, the sound turns into vibrations, which transmit in the middle ear via three small bones -- the incus, the malleus, and the sta...
It can transport sound through space silently — becoming audible only when desired. How did we do this? Normally, sound waves combine linearly, meaning they just proportionally add up into a bigger wave. However, when sound waves are intense enough, they can interact nonlinearly, genera...
Though popular thought contends that outer space is a vacuum, in actuality -- interstellar dust isso densein some areas that it can carry sound waves. Though these waves would be imperceptive to humans. Some sounds in space may include the humming of a massive black hole, the groans of Ea...
