Why can astronauts not talk to each other without communication equipment on the moon?
There is no air on the moon. Sound waves only propagate through a medium, such as air, water, etc. Sound waves cannot propagate through a vacuum, therefore the astronauts had to use radios to speak to each other.
How astronauts talk to each other in space?
yes they can communicate they have to
Why can astronauts hear on moon if they come close to each other so that their helmets touch?
Normally, to communicate in space, astronauts need radios. This is because sound (in this case, speech) requires a medium (such as air) to move through. In space, since there is no air, astronauts cannot talk to one another directly. However, in your case, the astronauts may converse because their helmets are touching - thus giving the sound waves a medium to move through - the helmets.
Why do astronauts use radio while talking to each other in outer space?
when they land , so they can communicate with each other. --- The term "Walkie Talkie" is a colloquialism which refers to a hand portable transceiver. Since every spacesuit is fitted with a hands-free transceiver then it is fair to say that they are always using one when suited up.
Can astronauts hear in space?
Sound doesn't propagate in space, or in any place without an atmosphere such as the surface of the moon. Sound is mechanical energy, and the energy must be "put into" the material (gas, liquid, solid) that is used to propagate it. This is in contrast to electromagnetic energy, like light, which is "self-contained" and can move through the vacuum of space. Astronauts can communicate by normal conversation inside a spacecraft or in the International Space Station. This is because pressurized air is introduced to simulate conditions on the earth (and allow astronauts to breathe). They can talk normally and be heard. But during a "space walk" or on the surface of the moon, all communication is by radio, even between individuals who are only a few feet apart. An interesting note is that two individuals who are "outside" can turn off their communications gear, press their face plates together, and have a conversation that no one else can hear. This lends new meaning to the term private conversation.
Why do astronauts talk on the radio?
That's the only way to communicate with sound where there is no air.
Why can't astronauts communicate with each other in outer space?
Astronauts can communicate with each other in outer space using radio waves. However, the lack of atmosphere in space means there is no medium for sound to travel through, so they can't talk to each other in the same way we do on Earth. Instead, they use radio communication systems built into their spacesuits or spacecraft.
How can astronauts communicate with earth if sound does not travel in a vacuum?
Astronauts communicate with Earth using radio waves, which can travel through the vacuum of space. Radio signals are transmitted from spacecraft to ground stations on Earth, enabling astronauts to communicate in real-time with mission control and other support teams.
Why can't you hear sound in space?
Sound requires a medium, such as air or water, to travel through. In the vacuum of space, there is no medium for sound waves to travel through, so it is impossible for sound to propagate. Astronauts can communicate with each other and with mission control through radio waves instead.
Why can't astronauts communicate with sound in outer space?
Because space is a vacuum.
Can you hear any sounds in space?
In space, sound does not travel because it is a vacuum, meaning there are no molecules to carry sound waves. Astronauts can communicate using radio transmissions inside their spacecraft, but they cannot hear sound like we do on Earth as there is no medium for sound to travel through in outer space.
If sound needs a medium to travel how do astronauts in space speak to people on the ground What kind of energy conversion is involved?
Astronauts communicate with people on the ground through radio waves, which do not require a medium to travel through space. This is an example of the conversion of sound energy into electromagnetic energy for transmission. On the ground, the electromagnetic waves are converted back into sound waves that we can hear.
Why did the astronauts have to use radios on the moon?
Astronauts on the moon used radios to communicate with mission control and other astronauts. The distance to Earth was too great for them to communicate in real time without radios. Additionally, the space suits and helmets they wore made it difficult to communicate verbally with each other.
How do astronauts speak in space?
Astronauts communicate in space using radio communication systems. They wear headsets with a microphone and speak into it to transmit their voice back to mission control on Earth or to their fellow crew members. The sound of their voice travels through the spacecraft or their spacesuit to be heard by others.
How quiet is it in space?
Space is completely silent because there is no air or medium for sound to travel through. This means that sound waves cannot be transmitted, resulting in complete silence. However, astronauts can still communicate using radio waves or vibrations within their space suits.
Can the astronauts talk on the surface of moon as on the earth?
Yes, astronauts can communicate with each other on the surface of the moon using radio communication devices in their space suits or spacecraft. The lack of atmosphere on the moon means that sound waves cannot travel, so they rely on technology for communication.
Why do astronauts need radios to talk in space?
Sound is carried by vibrations of molecules. When you talk here on Earth, air molecules transmit the vibrations and allow others to hear you. In open space there are very few molecules at all so there is nothing to carry the vibrations. Radios use radio waves to transmit information from one to another. These waves move through space by themselves so they can be transmitted from one astronaut to another. Then the radio turns the wave back into sound in the air filled compartment the astronauts breath in.
