How far can sound travel?
Sound cannot travel forever.
E.g, When someone is talking and there are lots of people around can't here them. This is because when you speak it causes the air molecules in front to bump into the air molecules in front of it to bump in to the other bunch, etc. This is how sound waves are are made.
One of the 3 states of matter, aka: gas, liquid, solid. Sound can't travel through nothing! A medium for the sound to travel through. Sound is caused by vibrations in something that cause vibrations in your eardrum. If there is nothing for sound to travel through, nothing to vibrate through to get to you, then there is no sound. Examples: Space is a vacuum, therefore no sounds can be heard. Water vibrates slowly with sound…
Sound will travel faster through any material that is more dense (i.e. the atoms are closer together) sound travels by vibration of particles, if an atom doesn't have to move as far to hit the next atom then the sound will travel much faster. This can actually be modeled really well by using pool balls.
At 20 degrees Celsius sound travels at 343 m/s (because: speed of sound= 331+ temperature*0.6). This means that it takes 1 second for sound to travel 34300 centimeters. If you take the inverse of this (1/34300=0.000029) then you'll see that it takes 0.000029 seconds for sound to travel 1 cm. You then multiply this number by the speed of sound (3e8m/s), and you have your answer: 8746.36 meters.
Sound does not travel on the moon because there are no air molecules for the sound to travel through. Sound only can travel if there's a medium for it to travel through, like air molecules, a liquid, or solids. Sound travels through vibrations. If there is nothing for sound to travel through, the sound can travel.
sound can travel past in solid because the molecules of solid is tightly closed and next liquid the molecules of liquid not so far away to each other and the slower is gas but it can travel longer than solid and liquid because the molecules in gas are far way and can move freely that can travel longer...
Most are based on sound waves. at a very basic level, they emit a sound that is outside of normal hearing range. The sound wave will reflect back to the range finder. The sound will travel at a known speed (aprox. 1000 feet per second). By calculating how long it took for the sound to travel to the object and return, you can determine how far away it is.
Surprisingly no. Air is a gas which means that the molecules are far apart. Even a liquid is better that air for sound to travel through because the molecules are closer together. But, a solid is the best for a sound to travel through. This is because the molecules are very close together so the vibration is transferred much quicker though the material.
Sound conduction through air is dependent on temperature and the strength of the sound, but sound can travel extremely far in the air. The 1883 eruption of Krakatoa volcano (Level 6 on the Volcanic Scale. The eruption was equivalent to a 200 megaton blast, or 13,000 times that of the Hiroshima bomb, and 4 times that of the largest nuclear device ever detonated, the Tsar Bomba, at 50 megatons. The eruption was heard over 3,000…
Indeed, sound waves will travel through a solid. Consider that you may overhear folk talking in the adjacent room. Sound is a vibration of air molecules, and these, when meeting a wall, will set the wall to move a (very) little. The wall in moving, will cause the air on the far side to vibrate in turn.
