Solved voice communication in space

[kf10]

voice can not travel in space

thats why we can not hear the nuclear explosion taking place on the sun

then how we communicate with astronauts in space

or how the people was able to hear the famous neil armstrong quote

small step for man and big step for mankind

from moon

Hello fellow Space Traveller,

There is this wonderful thing called the electromagnetic spectrum which describes all possible frequencies of electromagnetic radiation in our universe.

On one end of this range we find the short wave length gamma radiation, and on the other end we find the long wave length radio waves. We tend to use the radio wave length to communicate with astronauts since its too far to shout (I think the late Neil Armstrong tried it, but as far as I know we never heard it).

Somewhere in the middle of this spectrum we find the visible part of the radiation that allows you to read this post. If anything is unclear, just shout.

Regards,
Golden

And it's a good thing that we can't hear the explosions taking place on the sun. Can you imagine how loud that would be? All of the people/animals on this planet would most likely go DEAF from the mindboggling noise!!!!

i heard they used a couple of tin cans and a very big length of string

Can you hear me Major Tom

here is th reason from my cousin

In order for one to hear sound it must travel through air (gas particles) of which space has very few per cubic centimeter. Sound can only travel through a solid, liquid or gas. Space being an almost perfect vacuum does not allow sound to travel and be heard by the ears. Sound is vibrations of air particles, so any “sound” that is heard in space has to come from other means such as from the electromagnetic spectrum and these waves are not sound.

As such, astronauts communicate with each other in space when they are spacewalking through the use of radio waves. Radio wave signal are sent to their headsets which then translates the signal into the form of sound . When receiving and sending message to earth it is sent in the form of radio waves which is then translated to sound wave (message) by a radio set. Radio wave is a part of the light spectrum called electromagnetic spectrum and is therefore a light wave. Light does not need a medium to travel and this, further explains why the Sun’s light travels through space to earth. Light waves are not sound waves.

Astronauts can however, talk to each other as if they were on Earth only when they are in their space ship. Here, there are enough air particles to vibrate and take the sound to their ear drum.

Cool - I found the same explanation here:

no just asking for fun
