The longest radio wave would be the one with the lowest frequency. Wavelength is all about how far through space the leading edge of a wave travels before the "trailing edge" of one cycle of it leaves the broadcast antenna. For a frequency of 1 cycle per second (CPS), or 1 Hertz (Hz), that wavelength is almost 300,000 kilometers, or about 186,000 miles. That's a really, really long wavelength. You might be saying something about a frequency of 1/2 cycle per second or something like that. The wavelength will be double what it was for the 1 Hertz wave, of course. And for 1/4 cycle per second, it will be 4 times what it was for that 1 Hertz wave. There may not be a lower limit for frequency (or an upper limit for wavelength, which is the same thing), but there are practical limitations for what we can broadcast and what we can receive using current technology.

To get information into its carrier wave every radio station has to amplify the carrier wave?
False.
What type of electromagnetic wave is the largest?
The section we call 'radio'. Of course, there's no end to the electromagnetic spectrum, at least not on the low-frequency end, so there's really no such thing as "greatest" wavelength. As frequencies go down past radio and below, wavelength just keeps getting longer ... the bit of radiation from the 60 Hz utility power lines has a wavelength of almost 5,000 kilometers ( ! ! ). But we don't use anything down there in the form of radiation ... antennas would need to be gigantic in order to be the least bit efficient ... so there's no popular name for the radiated form. The 'generic' answer to the question is: The type with the lowest frequency.
What is the space wave propagation frequency?
Space wave propagation frequency is nothing special, it is the same frequency of the wave in question, for example WLAN Wifi produces 5.2 GHz radio wave from your computer or from router, so that would be the the space wave propagation frequency in question
How can you transform energy from one type to another like radio to electric?
Each type of energy conversion should be investigated separately. The example you mention - converting radio waves to electrical energy - works as follows: The electromagnetic wave (the radio wave) arrives at an antenna as an alternating electrical and magnetic field - so this will quite naturally induce an electrical current (alternating current).

What wave has the longest wave?
radio waves
What wave has the longest wave length?
radio waves
Which electromagnetic wave have the longest wavelengths?
The longest used is I think long wave radio which can be up to 1500 meters
Which type of wave has the longest wave- length?
Radio waves
What wave has longest wave length?
red
What type of wave has longest wavelength?
In the electromagnetic spectrum, it is the radio wave that has the longest wavelength. Some radio waves are over 100 yards long.
What is the longest wave length?
Radio waves are the electromagnetic waves with longest wavelength.
Does microwaves wave has the longest wavelenght?
No radio waves do.
Where on the spectrum is a radio wave?
A radio wave is the longest form of electromagnetic radiation, so it is just before microwaves, with nothing after it.
What are facts about radio waves?
It is the longest wave in the electroagnetic spectrum.
What is a wave with the longest wavelength and lowest frequency?
Radio waves
What has the longest wave length infrared radiation radio wave ultra violet radiation visible light micro waves gamma radiation or x rays?
Radio waves have the longest wavelengths.
