What is the fastest thing sound can travel through?
Scientists have discovered the fastest possible speed of sound, a zippy 22 miles (36 kilometers) per second. Sound waves move at different speeds in solids, liquids and gases, and within those states of matter — for instance, they travel faster in warmer liquids compared with colder ones.
How fast are the sound waves in water?
about 1,480 meters per second
What is faster speed of light or sound?
The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour.
Does sound travel faster in ice or water?
The speed of sound in ice is nearly 3 times faster than in water. The best way to conceptually approach the speed of sound in a medium is to think of the restoring forces (elasticity) and kinetic energy to be helping the sound wave, and any inertia (molecular mass) or extra density to be slowing down the sound wave.
What is faster than sound?
The speed of sound through air is about 340 meters per second. It’s faster through water, and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second. If you have light that’s going through media, it can travel slower than that.
Do sound waves exist forever?
First, let’s think about why sound does not travel forever. Sound cannot travel through empty space; it is carried by vibrations in a material, or medium (like air, steel, water, wood, etc). So, the sound wave gets smaller and smaller until it disappears.
Do sound waves travel forever?
The sound waves travel through the air bouncing off molecules and other solids like houses and trees. As the Waves move, they get farther apart. Therefore, to answer the question, sound waves only have a limited amount of time to travel, but yes, in fact they do travel after being emitted.
Can 2 astronauts hear each other in space?
There is nothing in space. There is no atmosphere. Even if the astronauts are floating in the atmosphere next to each other they can’t hear each other.
Can astronauts talk to each other in space?
Astronauts in space do talk to each other. In the spacecraft, there is plenty of air, so they just talk normally. When they are spacewalking, they talk by means of radios in their helmets. The radio waves, again, have no problem in space, but they’re not sound.
Why do astronauts wear white suits?
NASA astronauts wear white suits, since white is the color that reflects the most sunlight in space, and protects them from cancer-causing solar radiation.
Can you hear yourself scream in space?
Originally Answered: Can you hear yourself scream in space? No, space is a virtual vacuum. The only way you could hear yourself scream in space is if you were in a spacesuit with an available oxygen supply since sound waves require a medium to travel through. You’d feel your vocal chords vibrating though.
What happens if you yell in space?
If you get into a predicament in outer space, yelling won’t get you very far, because sound waves need a medium to travel through. Here on Earth, that’s usually air, although we can also hear quite well underwater. But wouldn’t it be cool to hear what vacuum actually “sounds” like?
What’s the farthest a person has been in space?
The record for the farthest distance that humans have traveled goes to the all-American crew of famous Apollo 13 who were 400,171 kilometers (248,655 miles) away from Earth on April 14, 1970. This record has stood untouched for over 50 years!
