What type of electromagnetic wave is the largest?

Answer 1

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.

Answer 2

== == Radio waves is the type of electromagnetic wave that has the greastest wave length.

Answer 3

If by largest you mean the longest wavelength, that would be a radio wave.

Answer 4

Gamma rays have the most energy. Gamma rays also have very high penetrating power. Gamma rays have smallest wavelength of all electromagnetic waves.

Answer 5

Extreme-low frequency radio waves. A three Hertz radio wave would have a wavelength of 100,000 km.

Answer 6

Those are the ones we call "radio" waves . . . anything with
a wavelength greater than roughly 1 millimeter.

Answer 7

Radio waves.

Answer 8

Radio wave.

Answer 9

Radio Waves
