Why can two astronauts not hear each other on the moon and in the space?
Sound is a mechanical wave and requires medium to propagate.
As the moon has no atmosphere, it has absence of air.
So, there is no medium for sound to propagate.
So, two astronauts cannot hear each other on the moon..
How do astronauts talk to each other on Moon and why?
Answer. Radio waves are used by astronauts to communicate with one another on moon because radio waves do not require any material medium for its propagation.
What do astronauts eat in space?
An astronaut can choose from many types of foods such as fruits, nuts, peanut butter, chicken, beef, seafood, candy, brownies, etc. Available drinks include coffee, tea, orange juice, fruit punches and lemonade. As on Earth, space food comes in disposable packages.
Why can we not hear any sound on the moon?
The air here on Earth allows sound waves to move from one point to another (sound can also move through water, steel, earth, etc… it just requires that particles/atoms/molecules are touching one another). … Thus there is no sound on the Moon.
How do astronauts hear each other in space?
Astronauts have devices in their helmets which transfer the sound waves from their voices into radio waves and transmit them to the ground (or other astronauts in space). This is how a radio at home works ��� radio waves are often thought to be a form of sound but they are not sound waves.
Can you hear a gunshot in space?
Firing a bullet is not much different in space than it is on Earth. … However, since there is no sound in space (as sound waves cannot travel in a vacuum), you wouldn’t hear the blast of gunshot. So, the first major difference is the built-in silencer for the gun. No sound of the gunshot.
How do astronauts sleep in space?
A crew member sleeps in a sleeping bag located in a crew cabin. … As a result, astronauts are weightless and can sleep in any orientation. However, they have to attach themselves so they don’t float around and bump into something. Space station crews usually sleep in sleeping bags located in small crew cabins.
Can astronauts communicate with Earth?
Because of the large distances involved, we can’t run any wires between the Earth and space. So the only way to send information back and forth is to use radio waves. … Astronauts can communicate with entire networks of amateur radio operators all over Earth!
Why can’t astronauts hear each other in space?
No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.
What does space smell like?
Astronaut Thomas Jones said it “carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous.” Tony Antonelli, another space-walker, said space “definitely has a smell that’s different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time, when I …
Can two astronauts talk in space?
No, the astronauts cannot talk on the surface of the moon because there is no atmosphere/medium present on the moon and sound cannot travel through vacuum. On earth air is present and hence they can talk with each other.
Why does an astronaut have to use electrical medium to talk in the space?
because in space there is no air. As we know that sound needs a medium to travel from one place to another. but in space there is no oxygen. so sound can’t travel there.
Do astronauts drink alcohol in space?
Alcoholic drinks are generally disallowed in spaceflight, but space agencies have previously allowed its consumption. NASA has been stricter about alcohol consumption than the Roscosmos, both according to regulations and in practice. Astronauts and cosmonauts are restricted from being intoxicated at launch.
Why do we not hear the screams of a bat?
Bats produce ultrasonic sound and thus humans cannot hear them.
