Which part of the electromagnetic spectrum is nearest to radio waves?

-X-rays

-microwaves

-gamma rays

-ultraviolet light

The part of the electromagnetic spectrum closest to radio waves is microwaves.

The wavelength of radio waves ranges from 10 cm to more than 1 km. The part of the electromagnetic spectrum that occurs closest to the radio waves is called the microwave region.

Microwaves have wavelengths ranging from around 1 mm to 10 cm.

The waves overlap in the region of 10 cm.

Thus, the region of electromagnetic spectrum closest to radiowaves is microwaves.

i think that the part of electromagnetic spectrum closest to the radio wave in the microwave. on the spectrum the microwaves wavelength is ranged from 1mm to about 10cm.
