Why Can Astronauts On The Moon Not Talk To Each Other Directly?
The sound waves are the longitudinal waves. … Therefore, if one astronaut speaks something to the other astronaut, there are no medium particles to transfer the sound wave to the other astronaut. As a result, the other astronaut cannot hear directly anything from the speaker astronaut.
How do astronauts speak to each other?
How do astronauts communicate with each other? … The astronauts have devices in their helmets which transfer the sound waves from their voices into radio waves and transmit it to the ground (or other astronauts in space). This is exactly the same as how your radio at home works.
Why astronauts Cannot talk to each other?
Because there is nothing out in space (like an atmosphere), the sound waves from one astronaut’s whistling can’t travel over to the other astronaut’s ears. That’s why the astronauts use radios to communicate—even if they’re floating in space right next to each other!
How do astronauts poop?
To poop, astronauts used thigh straps to sit on the small toilet and to keep a tight seal between their bottoms and the toilet seat. … There are two parts: a hose with a funnel at the end for peeing and a small raised toilet seat for pooping.
Can astronauts talk to each other in space?
When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. … That’s why the astronauts use radios to communicate—even if they’re floating in space right next to each other!
Can two astronauts on moon hear each other when they talk?
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 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.
Can sound heard 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 happens to a fart in space?
And there is actually air circulation on the ISS to keep astronauts from suffocating on their own CO2 exhalations, so farts get moved away, too. If you do end up going to space, there was one enterprising astronaut who found a way to belch without bomiting.
Do astronauts eat their own poop?
The scientists of the Penn University said that the new process includes mixing human excreta with microbes which will eventually turn it into edible substance.
Do astronauts poop in their suits?
Each spacewalking astronaut wears a large, absorbent diaper called a Maximum Absorption Garment (MAG) to collect urine and feces while in the space suit. The astronaut disposes the MAG when the spacewalk is over and he/she gets dressed in regular work clothes.
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.
How do astronauts stay cool in their suit?
Spacesuit insulation technologies protect the astronaut from extreme high and low temperatures of the space environment. However, the same insulation technology also works to keep heat released by the astronaut’s body inside the suit.
Why can sound not travel in 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.
Is there air on the Moon?
Despite their ‘airless’ appearance, both Mercury and the Moon have thin, tenuous atmospheres. With no detectable gases, the Moon appears to be atmosphere-free.
How do astronauts talk to each other on Moon and why?
Astronauts use the same devices to communicate with people on the ground. These sounds get converted to radio waves because of the air in the space suit. Thus, astronauts communicate with one another on the moon with the help of radio waves. So, the correct answer is “Option A”.
