No, radio signals can come from broadcasting towers and can be received by radios, without the need for satellites; indeed, radio broadcasting originated long before the first satellite was launched.
radio waves are propagated through the interaction of
Radio waves are in all parts of the atmosphere. Some, but not all, radio waves are reflected from the ionosphere, permitting transmission over greater distances.
Ionosphere
It's not radio active waves; it's just radio waves. It's called the Ionosphere and depending on what layer of the Ionosphere it changes how far you can talk
Of course, they are similar to visible light waves, just a different wavelength and frequency. Indeed, many electromagnetic waves (radio waves) can travel through solid objects and water depending on the frequency and the medium through which they travel. If radio waves couldn't travel through the atmosphere, your radio wouldn't receive a signal, hence no music.
Yes, radio waves can penetrate Earth's atmosphere. They are part of the electromagnetic spectrum and are able to pass through the atmosphere with minimal interference, which allows them to be used for various forms of communication, such as radio and television broadcasts.
Radio waves are useful under most weather conditions because they can pass through the Earth's atmosphere with minimal interference. This allows for reliable communication and broadcasting even during inclement weather such as rain or fog.
I dont think they do, Radio waves diffract less and arn't affected by the ionosphere which is the upper part of the atmosphere. Most electromagnetic waves are affected severely by the atmosphere, which is a good thing due to the strength they carry EXCEPT microwaves *Apparantly*.
By the earths atmosphere
radio telescopes
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.
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.
Radio waves travel through the atmosphere by being transmitted from a radio station's antenna. These waves travel in a straight line until they encounter an obstacle, such as the Earth's surface or a building. They can also be reflected off the ionosphere, a layer of charged particles in the Earth's atmosphere, which allows them to travel long distances. Once the radio waves reach our devices, such as radios or cell phones, they are converted back into sound or data that we can hear or see.
Radio waves are useful under most weather conditions because they can pass through the atmosphere without significant disruption. This makes them reliable for communication purposes, such as broadcasting radio signals or transmitting data wirelessly. Additionally, they are less affected by factors like fog, rain, or snow compared to other forms of electromagnetic waves.
Magnetic fields can affect the propagation of radio waves by causing them to bend or refract as they travel through the atmosphere. This can result in changes to the direction and strength of the radio waves, impacting communication and signal quality.
The longest wavelengths are radio waves, which can range from several centimeters to kilometers in length. These waves are used for communication, radar, and broadcasting due to their ability to travel long distances through the atmosphere.
