7/23/2023 0 Comments Speed of sound per second![]() Where $c$ is the speed of light, and $p$ and $\rho$ are the pressure and density of the gas. This creates oscillations, or sound waves with tremendously long wavelengths. We assume you are converting between speed of sound air and metre/second. How many speed of sound in 1 meters per second The answer is 0.002938669957977. But as a clump grows, pressure from baryons and photons increase, counteracting the collapse, and pushing baryons and photons outwards, while the dark matter tends to stay at the center of the overdensity, since it doesn't care about pressure. More information from the unit converter. Stuff was still slightly clumpy, though, and the clumps grew in size due to gravity. Speed of sound in the primordial soupĮverything was very smooth, no galaxies or anything like that had formed. 500000 Miles per second 2345982.48 Speed of sound: 9 Miles per second 42.2277 Speed of sound: 1000 Miles per second 4691.96 Speed of sound: 1000000 Miles per second 4691964. The result- about 36 km per secondis around twice as fast as the speed of sound in diamond, the hardest known material in the world. The photons themselves couldn't travel very far, before hitting a free electron. ![]() This temperature was so high, that neutral atoms couldn't form any electron caught by a proton would soon be knocked off by a photon (or another particle). 1 Speed of sound 0.2131 Miles per second: 10 Speed of sound 2.1313 Miles per second: 2500 Speed of sound 532.83 Miles per second: 2 Speed of sound 0.4263 Miles per second: 20 Speed of sound 4.2626 Miles per second: 5000 Speed of sound 1065.65 Miles per second: 3 Speed of sound 0. In contrast, the speed of sound in air is roughly 767 mph (1,235 km/h). ![]() they shared the same (average) energy per particle, or temperature. Scientists have discovered the fastest possible speed of sound, a zippy 22 miles (36 kilometers) per second. Compare your experimental value to the true value. By popular demand (considering two to be popular - thanks Vance and Learning), I'll expand a bit on my comment to Hunt's answer: Thermal equilibriumĪs I said in the comment, the notion of sound in space plays a very significant role in cosmology: When the Universe was very young, dark matter, normal ("baryonic") matter, and light (photons) was in thermal equilibrium, i.e. The speed of sound in air is 343 m/s (nearly a mile in 5 seconds) at 20C. ![]()
