One convenient working definition of 'radio' is: Electromagnetic radiation with
frequency up to 300 GHz / wavelength down to 1 millimeter.
'Radio' is our name for the lowest frequency / longest wavelength, so there's
no lower limit on frequency, or upper limit on wavelength.

Which kind of waves are the longest Radar waves Radio waves Visible Light or Gamma Rays?
for wavelength, the longer of the two is visible light, but the longest type of rays are radio waves (some of them have a wavelength as long as a football field)
Describe the difference between radio waves visible light and gamma rays?
frequency energy wavelength
Which type of radio waves have highest frequency and are used in radar detection?
microwaves
What is the difference between microwaves and radio waves?
They are the same thing; vibrations of the electromagnetic field. Microwaves have a frequency between 0.3 GHz to 300 GHz, and radio waves have a frequency between 3 Hz to 300 GHz. So microwaves are a type of radio wave.
What type of radiation has the shortest wavelength of radio waves or cosmic rays or ultraviolet light or infrared light?
X-rays have the shortest wavelength of those listed.
What type of wave has the longest wavelength and the lowest frequency?
I think it is radio waves!
Which type of em spectrum has the highest wavelength?
The energy of EM radiation depends on its frequency, and the lowest frequency corresponds to the lowest energy. Radio waves are at the low end of the energy and frequency spectrum.
Which types of electromagnetic waves are used for radio communication?
Those are called radio waves. Also, the so-called microwaves, which are basically a type of radio waves (with a relatively high frequency and short wavelength), too.
Is infrared a type of radiation ray?
yes so is am fm radio and tv signals
Which type of waves have a frequency of 100000 Hz?
Ultrasound or quite-low-frequency radio waves have.
What type of light has a wavelength of 1 kilometer?
Radio waves
What type of EMR has the longest wavelength?
A photon is a fundamental or elementary particle and the carrier of the electromagnetic field. In this light (no pun intended) it can be applied to all electromagnetic energy, including radio waves. There wouldn't be a "lowest frequency" of electromagnetic radiation that was not photonic. ---- ...or if there was it would have a wavelength the size of the Universe : ) Couldn't carry a whole lot of data there...
What type of wave has the has the lowest frequency?
Radio waves in electromagnetic waves/water waves
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 formula for the Universal Wave Equation?
I am pretty sure that there are many formulae for working with waves. It also depends what type of waves you are working with. One important formula, that applies to all sorts of waves, is this simple relationship: speed (of the wave) = wavelength x frequency
Which kind of waves are the longest Radar waves Radio waves Visible Light or Gamma Rays?
for wavelength, the longer of the two is visible light, but the longest type of rays are radio waves (some of them have a wavelength as long as a football field)
What kind of waves are microwaves?
Electromagnetic waves, just like light, but with different frequency and wavelength.
