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 does the ionosphere help us?
The ionosphere has the useful property of reflecting radio waves, thereby enabling us to send radio signals past the horizon.
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.
How can ionOsphere can help us communicating?
The ionosphere has the useful property of reflecting radio waves, thereby enabling us to send radio signals past the horizon. [copied from an answer to a substantively identical question]

What are the importance of sound waves?
sound helps us to communicate with each other
Does the alphabet help us to communicate?
no
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).
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.
How can radio waves be used to observe stars?
1) Any object that emits radiation (because of its temperature) will emit in all wavelengths, including visible light, infrared, radio waves, ultra-violet, etc.What changes is the proportion of each (which depends directly on the temperature).2) The Earth's atmosphere is transparent to radio waves (meaning: it is easy to receive radio waves from space -- in general they are not blocked by the atmosphere).3) It is easy to build a receiver that gives us the direction from which the radio waves are coming. We can draw maps of radio sources (the same way that taking pictures in visible light lets us draw maps of the visible stars).
What bounces radio waves back to the earth and protects us from radiation from the sun?
ozone layer
Do astronauts' voices need to be converted into gamma rays before getting to us?
Radio waves do the trick.
Why do you have speech?
To have a speech help us to communicate which make us more social attached organism
