How fast is the speed of sound?

1,000000,0000000 that is how fast sound really is.\n\nbut to answer you question just listen and watch a jet after the jet passes then it takes 15 seconds before you here the sound because the jet has broken through the sound barrier.

Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air. The exact speed of sound in steel is 5,960 meters per second (13,332 mph)! But, this is only for the majority of solids. The speed of sound in all solids are not faster than in all liquids.

The question asks nothing about the speed of sound in air compared with water. I believe that the answer is that sound will travel farther through air than water. \n\nMy reasoning is as follows:\n\nSound is a compression wave and its propagation is based upon atoms and/or molecues "bumping into" each-other in order to convey the energy of the sound. Now, with each collision between atoms/molecules, some energy is lost due to heat, so the more collisions there are (eg water), the more energy is lost. The fewer collisions there are (eg air) the less energy is lost. Of course, as everyone has pointed out, water is more dense than air, so there are more collisions per metre in water than in air, and so more energy loss per metre in water than in air.\n\nTherefore sound will travel farther in air than in water. \n\nAnother way to look at it is by taking it to the extreme. Let us imagine for a moment that there is a lonely molecule in outer space and we "bump" it with a spaceship. It will travel through space unimpeded, carrying that energy until it finds another molecule to bump into, maybe millions of kilometres away. So, that energy the spaceship imparted onto that molecule has travelled millions of kilometres. We can't hear a single molecule hitting our eardrums, but the effect is the same.\n\nAnyway, I hope that analogy helps.

186,000 miles a second vs 220 some odd miles per second?  yeah, it is\n\nedit- \nok, to the person below, yes, I meant per hour, and was lowballing it... \n\nspeed of sound at sea level = 340.29 m / s

The speed of light. 186,000 miles per second.

Depends on the media in which it propagates. The temperature and the pressure also slightly affect the speed. In air it's about 330 m/s.

Great question!  For the speed of sound, I think the best demonstration is an outing where you can place a line of student about 100m apart.  Give each a flashlight with a button.  Get out your video camera and place it on a roof or hill so you can record all of the students.  Then rig a simple light on a sound source at one end of the line.  For instance, a sledge hammer on a piece of steel with a circuit between them.  Make sure the student banging the drum has earplugs!  At ~340 m/s in normal air, you only need ten students or so to make this effective.  Then just digitize the tape and have them count the number of frames between each light turning on.  You can also talk about human reaction times as a bias.\n\nFor the speed of light, check out the link.  It is doable, but a bit more technical, and not as obvious as the above.\n\nHope that helps!

The speed of sound varies depending on the material it is travelling through, the pressure, altitude and temperature.\n\nOn the assumption you're talking about air and that you're at sea level under normal atmospheric conditions then 340m/s would be the speed at 14 degrees C and 330m/s would be the speed at minus 1 degree C - so they're both right.

since the humidity is low, It is reasonable to neglect the humidity factor since the T is same the speed of sound can also taken as constant.\nspeed = distance by time\ntherefore time = 400 / 343 s.\n               = 1.16610875801749 s.

The speed of sound in air depends on the temperature of air, and the composition of the air (different amounts of gases or water vapor present ).\nAt 0 degrees Celsius (freezing point), the speed of sound in regular dry atmospheric air is 331.4 meters/second (or 742 miles per hour).\nAt 22 degrees Celsius (71 degrees F), the speed of sound is 344 m/s (772 mph).\nAt 100 degrees C (boiling point), the speed of sound is 392 m/s (878 mph).\nYou can use the link to calculate the speed of sound for any temperature.

If we consider the atmosphere on a standard day at sea level static conditions, the speed of sound is about 761 mph.

Sound waves are longitudinal waves. They vibrate back and forth in the direction that they aremoving. Sound travels at about 1100 feet /sec.\n\nLight waves are transverse waves, part of the electromagnetic spectrum. they vibrate up and down similar to water waves. They travel at 186,000 miles/sec.

Values of the Speed of Sound:\n\nOne of the most common questions we receive is fow fast is the speed of sound, and as was pointed out earlier, there is no single value to quote. The speed of sound, also known as Mach 1, changes throughout the atmosphere based on the temperature at any given altitude. Probably the most important value to remember, however, is the speed of sound at sea level. Based on the standard atmospheric model, this value has been defined to be\n\n    * 1,116.4 ft/s\n    * 340.3 m/s\n    * 761.2 mph\n    * 1,225.1 km/h\n    * 661.5 knots\n\nIf you were to reach Mach 1, or "break the sound barrier," at sea level, the above speed is how fast you would have to travel in order to do so.

You tell me, you the one doing the lab probably.\n\nOne of several possible objects could be to identify the speed of sound.  You might also be studying the nature of waves (wavelength, frequency, ...).

Yes, light travels faster than sound. You can tell from several \nexamples. The best would probably be that of lightning and thunder. The next \ntime during a storm, if you notice when lightning flashes across the sky and \nwhen you hear thunder, you will find that it is always the lightning that \nflashes before the thunder. This is because lightning (i.e. light) travels \nfaster than thunder (i.e. sound), and reaches you faster, so that you see the \nlightning before you hear the thunder. In fact, light is enormously faster than \nsound. Light travels at 300,000,000 metres per second (i.e. 300 million metres \nper second), while poor old sound travels only at 330 metres per second.

sound travels at an avg speed of .78999342 mps or 2843.9763 MPH in seawater depending on water temperature salinity and depth of the source/receiver.\n\nlight averages 186,282 mps or 11,176,920 mph\n\nthe other answers AREN'T WRONG but you should have specified through what medium they are traveling. also you need to specify temperature humidity pressure altitude/depth salinity and or a myriad of other factors\n\nLight has a different speed when passing through our atmosphere than it does through space just as sound through air and water or a solid. the more dense the material the faster the sound transmission. oddly the opposite is true for light.\n\nthis question has been asked several times before.  if you do a search for previous questions you will doubtless find MANY other answers for these very questions with more precise speeds through different mediums.

Speed of waves = wavelength X frequency of waves.
