Why does the sound of an engine gets quiter as it moves away?
It takes energy for sound to travel through air, and sound is energy. So the more air the sound has travelled through the less sound there is left.
How far does light travel in the time it takes sound to travel 1 cm in air at 20 C?
Based on the speed of sound being 340 m/s and that of light being 299,792,458 m/s. we get the speed of light being ~881,742 times that of sound. So if sound goes 1cm then light will travel 881,742 cm or 8,817.42 m.
Why does sound travel slowly through gas?
Sound travels slowly through gas because the particles in a gas are further away then the particles in a solid or a liquid. This makes it take longer for the sound waves to travel through the particles in gases because it takes longer for them to collide with each other; this makes it take longer for the particles to pass on the sound vibration.
Can compression waves be transmitted through a vacuum of space?
no the only waves that can go through space is the electromagnetic waves and it doesnt need sound or matter to travel.compressional waves have to come off of something and travel{like sound} it cant travel because there is nothing to travel through.the vacuum of space is just nothing and only light can go through as well, but it takes time.
Why does sound travel slower through liquids?
It doesn't, sound travels slowest in air then faster in liquids then solids. Sound traveling through steel in many times faster then through air, for example. Sound travels through vibrations, and the vibrations pass through molecules until they reach your ear. If the molecules are far away it takes longer to pass the vibrations, but if they are closer together they will travel faster. Because the molecules are packed closer together in a liquid the sound travels faster through it, and even faster through solids.
How long does it takes sound to travel 100mm?
0.000292 second
What is an example that demonstrates that sound takes time to travel?
Fire crackers or thunder and lighting.
Why does sound travel slowest thru gases?
Gases have the least amount of molecules and they are spread farther apart so it takes a longer time for the sound energy to travel from molecule to molecule.
Why does the sound of an engine gets quiter as it moves away?
It takes energy for sound to travel through air, and sound is energy. So the more air the sound has travelled through the less sound there is left.
How time taken to the nearest second for sound to travel 1km?
It takes 3 seconds.
When the temperature is higher does sound travel faster or slower?
as in summers the particles are far apart from each other so we can say that in low temperature sound moves faster because it needs a material medium to travel. as in winters that is low temperature their are a lot of particles in air so this helps the sound to propagate and takes less time to travel. n in summers that is high temp. the particles are apart so it takes more time to travel.
What is the second report sometimes heard when a rifle is heard from a distance?
The FIRST sound would be the crack of the bullet making a sonic boom- most travel faster than the spped of sound. The second is the sound of the gun firing- it takes longer for the sound to get to you than the bullet takes to get to you.
How far does light travel in the time it takes sound to travel 1 cm in air at 20 C?
Based on the speed of sound being 340 m/s and that of light being 299,792,458 m/s. we get the speed of light being ~881,742 times that of sound. So if sound goes 1cm then light will travel 881,742 cm or 8,817.42 m.
How long does it takes a sound to travel a distance of 1900 feet?
In dry air at sea level and atmospheric pressure, 1.69 seconds.
Simple experiment to compare steel and cast iron?
A steel specimen would give a longer or continuous sound when beaten by a hammer. This is due to the malleable nature of the material. In other words, sound takes longer to travel in a coarse-grained material. Whereas cast iron specimen gives sound of shorter duration. This is due to the brittle nature of the material. In other words, sound takes shorter to travel in a fine-grained material.
What travels faster the speed of light or the speed of sound?
The speed of light is nearly a million times faster than the speed of sound.The speed of light is roughly 882 thousand times the speed of sound.-- Sound takes about 4.7 seconds to cover 1 mile.-- Light takes about 0.0000054 second to cover 1 mile.-- In the time it takes sound to travel one mile, light travels 881,741 miles .
How long does it take for light and sound to reach earth?
The length of time it takes light to reach earth has a lot to do with where it starts out from. If it starts from the moon, it takes about 1.5 seconds. If it starts from the sun, it takes about 8 and 1/3 minutes. If it starts from the nearest star, it takes about 4.4 years. If it starts from the North Star, it takes about 230 years. If it starts from the Andromeda Galaxy, it takes about 2.5 million years. Sound can't reach the earth from any other body. Sound needs air to travel through, and there's no air past a couple hundred miles above earth's surface. Sound can't even travel between two astronauts standing on the moon 2-ft apart.
