Sound does not travel at all in space. The vacuum of outer space has essentially zero air . Because sound is just vibrating air, space has no air to vibrate and therefore no sound. ... Radio is a form of electromagnetic radiation just like light and can therefore travel through the vacuum of space just fine.
Can sound be in space?
It's long been said that there's no sound in space , and that's true, to a point. Conventional sound requires a medium to travel through, and is created when particles compress-and-rarify, making anything from a loud “bang” for a single pulse to a consistent tone for repeating patterns.
Why can sound not travel through space?
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate .
Why does sound not travel in space quizlet?
Sound can travel through all kinds of matter, including solids, liquids, and gases. Sound travels more quickly through solids and less quickly through gases. Sound cannot travel through space because there is no matter in space . How do we know that sound transfers energy?
Can you smell a fart in space?
In space, no one can hear you fart (but they can smell it) . They can! Zero gravity could even help them to travel, if the aroma was spreading through a virtual vacuum. Smells travel by the movement of individual aroma molecules.
Does space have a smell?
In a video shared by Eau de Space, NASA astronaut Tony Antonelli says space smells “strong and unique ,” unlike anything he has ever smelled on Earth. According to Eau de Space, others have described the smell as “seared steak, raspberries, and rum,” smokey and bitter.
What's the loudest thing in the universe?
As far as I'm aware, the Perseus galaxy cluster is the current record holder for the loudest sound discovered in the Universe. Generating sound requires two conditions. First, there must be a medium that the sound waves can travel through, like air or some other gas.
What is the loudest thing in the world?
The Krakatoa volcanic eruption : Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB. It was so loud it was heard 3,000 miles (5,000 km) away.
What is the loudest thing on earth?
The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27 , 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.
Can sound waves travel in a vacuum?
Sound waves are travelling vibrations of particles in media such as air, water or metal. ... So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
Which medium will sound travels the fastest?
Of the three phases of matter (gas, liquid, and solid), sound waves travel the slowest through gases, faster through liquids, and fastest through solids .
Can sound travel in a vacuum quizlet?
Sound cannot travel through a vacuum , because it needs matter to vibrate and travel through. ... Molecules are closest together in solids, so sound travels most quickly through this medium. As the distance between molecules increases, the speed of the sound wave decreases.
What happens if an astronaut gets pregnant in space?
Even though existing and proposed space conveyances have improved radiation protection, they don't contain nearly enough shielding to allow zygotes to develop. And even if a baby was able to make it out of the womb, it would have a high probability of birth defects from the radiation damage .
Do female astronauts wear bras in space?
The answer (according to one astronaut, at least) is “ Yes “: Astronauts spend more than two hours a day exercising. ... That's a lot of stress, so sports bras are commonly used during exercise.
Can u fart in space?
Air is lighter than solids and liquids, which is why it rises in your stomach and you can easily burp up gas on Earth. The lack of gravity in space means the air in astronauts' stomachs doesn't separate from ingested food, so burping could expel more than just gas.
Has anyone been lost in space?
A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. All seven crew members died, including Christa McAuliffe, a teacher from New Hampshire selected on a special NASA programme to bring civilians into space. ...
