Final answer:
An electromagnetic wave with a wavelength of 10 microns is classified as infrared radiation in the electromagnetic spectrum.
Step-by-step explanation:
An electromagnetic wave of wavelength 10 microns (which is equivalent to 10 micrometers or 10 x 10-6 meters) falls into the infrared portion of the spectrum. The electromagnetic spectrum is ordered by wavelength and frequency where radio waves have the longest wavelengths followed by microwaves, and then infrared. The correct order as per the references provided is: radio waves, microwaves, infrared, visible, ultraviolet, X-ray, and gamma rays. Because 10 microns is greater than the wavelength range for ultraviolet radiation (10 to 400 nanometers) and is less than microwaves, it classifies as infrared radiation. Thus, the correct part of the electromagnetic spectrum for a 10-micron wavelength is infrared radiation.
