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.
== == Radio waves is the type of electromagnetic wave that has the greastest wave length.
If by largest you mean the longest wavelength, that would be a radio wave.
Gamma rays have the most energy. Gamma rays also have very high penetrating power. Gamma rays have smallest wavelength of all electromagnetic waves.
Extreme-low frequency radio waves. A three Hertz radio wave would have a wavelength of 100,000 km.
Those are the ones we call "radio" waves . . . anything with
a wavelength greater than roughly 1 millimeter.

both electric and magnetic energy
Generally visible light and/or ultra-violet.
EMP or electromagnetic pulse. It can disrupt electronic systems, and signals.
An electromagnetic wave is properly called a Transverse Electro Magnetic wave, or TEM wave. It consists of an alternating magnetic wave at right angles to an alternating electric wave, with both fields being at right angles to the direction of propagation. The plane of the electric field is defined as the plane of polarization.
It is microwaves that are used for radar. They are high frequency, short wavelength electromagnetic waves, and a number of different frequency ranges of these microwaves are used depending on the application. A link is provided to the Wikipedia article on radar and the different bands or ranges of frequencies that are used and their applications.
Radio waves are a type of electromagnetic wave.
Light is an example of a electromagnetic wave.

The electromagnetic wave used here is Ultraviolet wave...
An electromagnetic wave is a radiant wave.

It is a high energy electromagnetic wave.

No. Sound is a mechanical wave, not an EM wave.

If you mean a wave on a string, no - that's a different type of wave.
It is a high energy electromagnetic wave.
