When we talk about the speed of sound, what exactly do we mean? Now you know that sound carries energy in a pattern of waves, you can see that the speed of sound means the speed at which the waves move—the speed at which the energy travels between two places. When we say that a...
分析 声音在空气中的传播速度是大约每秒340米. 解答 答案:travels.声音在空气中的传播,这是一个自然现象,所以要用一般现在时.根据主语是sound,结合英语提示travel,所以要用travels.故填travels. 点评 有些自然规律的事情,要用一般现在时,首先要确定时态,然后结合给出的英语提示,就可以确定答案.练习...
aLight travels at a speed which is about a million times faster than the speed of sound. You can get some idea of this difference by watching the start of a race. If you stand some distance away from the starter, you can see smoke from his gun before the sound reaches your ears. 正...

A sound wave travels at a speed of 339 m s^-1. If its wavelength is 1.5 cm, what is the frequency of the wave? Will it be audible?
Therefore, sound travels much faster through solids than through liquids or gas. When understanding the speed of sound through different mediums or materials, there are several factors to consider besides density. 1. Elastic Properties Elastic properties are the properties of a material that allow ...
