What else can I help you with?
How fast can a radio wave travel to space and back to earth?
Radio waves travel at the speed of light which, in a vacuum, is about 3 x 108 meters per second.
What was invented in 1932?
radio waves
Do radio waves need medium to travel?
light waves do not need a medium. Electromagnetic Waves (EM) do not need a medium. For example visible light, radio waves, microwaves, UV light and x-rays do not. These travel @ 300 million meters/sec in a vacuum.
Which EM waves can carry television signals?
Radio waves. Low frequency.
How a triode works as basic amplifier?
A triode works as a basic amplifier by the use of radio waves. The radio waves produce a heat that is amplified.
What happens when radio waves hit the earth?
When radio waves hit the Earth's atmosphere, they can be absorbed, reflected, or refracted. Some radio waves may continue through the atmosphere and reach the Earth's surface, where they can be picked up by antennas and receivers for communication or broadcasting purposes. The Earth's atmosphere allows radio waves to travel long distances without much degradation, making them valuable for long-range communication.
Does the ionosphere bend radio waves back toward the earth?
it refracts the radio waves back towards the earth
Neither X rays nor radio waves can penetrate the earth's atmosphere?
False. For some bands of radio waves the atmosphere is transparent. Radio waves can penetrate to the ground. That's why we have radio telescopes on the Earth.
Radio waves bounce and return to earth?
The Radio waves are reflected back to Earth in the Ionosphere.
How do you communicate to earth from space?
radio waves
How do you communicate earth to space?
radio waves
What layer of the atmosphere send radio waves back to earth?
The troposphere... It acts like a gigantic mirror - reflecting radio waves back to Earth.
radio waves heading upward from earth often bounce off the ____.?
ionosphere
What layer reflectes radio waves back to earth?
The ionosphere contains weakly ionized gas which reflects radio waves.
Why are satellite used to relay radio waves?
Satellites are used to relay radio waves to the other side of the world because radio waves cannot travel directly through the Earth.
Part of atmosphere used to bounce shortwave radio waves?
Radio waves bounce off of the ionosphere and return back to Earth.
Which electromagnetic waves are used for communication in space?
Radio waves are predominantly used for communication in space due to their long wavelengths that enable them to travel long distances without much interference. These waves are able to penetrate Earth's atmosphere and travel through space to reach distant spacecraft and satellites.
