Speed of sound is the speed at which sound waves move through the mediums like gas, liquid, solid and vacuum. The speed of sound in dry air is 343 m/s.
The speed of sound in air is definite. But the speed of light in a vacuum is much ___. A. definite B. indefinite C. fast D. slow 相关知识点: 试题来源: 解析 C。“definite”在这里不是反义词的考查点。声音在空气中的速度是确定的,而光在真空中的速度比声音快很多。考查了对不同物理现象...

The speed of sound in the tenuous Martian atmosphere had been theoretically predicted by assuming that the idea gas law applies to this very low-pressure case. In this paper, we present the experimental results of the measurements of the speed of sound in a cylindrical vacuum chamber by using...

speed of sound Sound waves travel at approximately 750 mph at sea level, but slow down at higher altitudes. The speed of sound is called "Mach 1." Supersonic refers to speeds from Mach 1 to Mach 5 (1 to 5 times the speed of sound), and hypersonic ranges from Mach 5 to Mach 10 ...
In general, any non-canonical k-essence model has an evolving speed of sound. One has to choose a model in such a way that the sound speed is always subluminal because we do not expect any information to propagate faster than the speed of light in a vacuum. Also, the sound speed has...

vacuum-sound waves. Taking the electron-neutrino as the corresponding par- ticle, its observed non-vanishing rest-energy may only appear for neutrino- propagation inside material media. The idea may also influence the physics of dense matter, restricting the maximum speed of sound, both in v...
