they use high frequency sound waves to penetrate deep into the atmosphere and possibly a black hole if you are lucky
Astronauts when they do not work, sleep, or as in the Skylab had a day for having a wash and clean up, they had radio work as well.
Exactly the same way it works anywhere else, only better.
Electromagnetic radiation.
Depends on what you mean. Speakers need air to work, so outside a spaceship they wouldn't be able to make any sound. Radio waves work just fine in vacuum, but the extreme temperatures are quite likely to kill electronics intended for room temperature. Ignoring the issue of hardware survival there's also the question whether ordinaly commercial transmissions would reach into space or not. Even if the radio is working there might not be anything to listen to.
They have a great website. Please check it out. SETI stands for the Search for Extraterrestrial Intelligence. It is a project which started in 1959 to search for radio signals from intelligent life in space. The SETI project uses radio telescopes from around the world to scan the sky and look for special patterns in radio waves which could have been sent by another civilization in space. Radio telescopes are used because radio waves can travel very far in space without being absorbed by the thick clouds of gas and dust which lie in many regions of space. Also, radio telescopes can be used both day and night. We have been sending out our own radio waves into space for over sixty years. All of our radio and televison signals travel into space at the speed of light and may one day be detected by another civilization in space.
Radio waves work through execution of a physical concept known as simple harmonic motion. These waves are really sounds that travel in a wave-like pattern through the push of air as well as their own internal oscellations. When these waves reach one's ears it is possible to hear the sound they transmit.
Pagers work by using radio waves. Messages are sent via touch-tone phone, where the person sending the message types a text using their number key pad. The message is then displayed on the pager's screen.
how does the radio work because i can't cange it because i was it to be on 105.7
It depends on - the radio market you work in - the company you work for - your level of radio programming experience
No.
Sirius radio won't work overseas, unfortunately.
The radio will work fine, but there will be nothing to hear.
