What else can I help you with?
Radio waves and useful of radio?
how are radio waves be used- well they are used by sound waves like as in u can hear sond waves but radio waves is where you are in the car and u are listening for instance capital fm that is radio waves Hope It Helped Hennddyyyy:) :D
What does radio mean?
A radio that receives Frequency Modulated (FM) transmissions.
What level of the atmosphere bounces radio waves back to earth and protects us from radiation from the sun?
The Ionisphere bounces radio waves back to earth and regulates the amount of radiation that gets to the lower atmospheres. It all depends on the Sun's activity. The stratosphere is what actually protects us from the UV rays of the sun. The stratosphere creates the ozone layer to keep the UV rays out.
How does the radio help us in the day to day life of a human?
A radio programme receiver does not need to be directly in view of the transmitter to receive programme signals. For low frequency radio waves diffraction can allow them to be received behind hills, although repeater stations are often used to improve the quality of the signals.
Do radio waves have the shortest wavelength?
First of all, your question is not worded all that well. When we speak of a wave, in this case an electromagnetic one (as opposed to one made of water perhaps), we tend to describe them quantitatively with certain numbers. One may speak of the frequency of the wave (measured in Hertz), the energy of a wave (in joules), or, in your case, the wavelength of a wave (in metres). The electromagnetic spectrum is usually taught to span from radio waves (waves with relatively large wavelengths and low frequencies) to gamma rays (waves with relatively small wavelenths and very high frequencies). The misunderstanding you seem to have is that the electromagnetic spectrum stops at radio waves. It does not. In theory, the electromagnetic spectrum is infinite and continuous. That is to say, there is no limit to how large a wavelength can be nor how small one can be. The electromagnetic spectrum susually stops at radio waves (with a typical wavelength ranging from 1 to 10 metres) because waves longer than these lose their practicality. In theory, they exist, but they simply are not as important to us than their shorter cousins!!! Just as a side note, "long waves" are said to have a wavelength of around order 10^3 metres (or just around the order of a kilometre). Theoretically, I can imagine it possible to have a wave with a wavelength as long as the universe itself! Of course, as I mentioned earlier, such waves are of little practical value to us. As a result, yes it does have the "longest" waves.
How do satellite dishes help us?
They help us communicate with the (artificial) satellites. We can receive tv and radio programs from them, we can bounce telephone and data communication off them and so on.
What do waves allow us to do?
Waves allow us to communicate over long distances, transfer energy, and observe distant objects in space through technologies like radio, sound waves, and light waves. They play a significant role in various aspects of our daily lives, from wireless communication to medical imaging.

Does the alphabet help us to communicate?
no
How does the ionosphere help us?
The ionosphere helps us by reflecting radio waves, which enables long-distance radio communication. It also plays a crucial role in regulating the Earth's climate by absorbing harmful ultraviolet radiation from the sun. Additionally, the ionosphere allows for the existence of phenomena like the Northern Lights.
What is an example of how em waves can harm us and how em waves can help us?
Example of harm: Prolonged exposure to high-energy electromagnetic waves, such as X-rays and gamma rays, can damage cells and cause cancer. Example of help: Low-energy electromagnetic waves, such as visible light and radio waves, are used in technologies like communication devices, medical imaging, and cooking appliances to benefit society.
Can you explain how radio waves compare to visible light waves?
Radio waves and visible light waves are both forms of electromagnetic radiation, but they differ in terms of their frequencies and wavelengths. Radio waves have longer wavelengths and lower frequencies compared to visible light waves. This means that radio waves have lower energy and are used for communication purposes, such as broadcasting radio signals. Visible light waves, on the other hand, have shorter wavelengths and higher frequencies, allowing us to see the colors of the spectrum.
How a radar helps us?
AnswerRadar Help to detect object at the space and also transmit the pulses of radio waves which bounce off any object in their path.
What energy transformations take place in a radio?
In a radio, electrical energy from a power source is converted into electromagnetic energy (radio waves) by the transmitter. The radio's antenna captures these radio waves and converts them back into electrical signals, which are then converted into sound waves by the speakers, thus transforming the energy back into sound energy for us to hear.
Where do you find radio-waves?
They are all around us. Radio waves are emitted by radio and television stations; they are also used by wireless communications (for example, Wi-Fi, Bluetooth).We also receive radio waves from outer space; for example, from AGNs (active galactic nuclei).
What bounces radio waves back to the earth and protects us from radiation from the sun?
ozone layer
What is the useful energy in a radio?
The useful energy in a radio is the electrical energy converted into radio waves that transmit sound through speakers, allowing us to listen to music or news.
