Microwaves have wavelengths that are longer than visible light, infrared, and ultraviolet radiation, but shorter than radio waves. They fall within the radio spectrum and are invisible to the human eye. Therefore, they have a small wavelength relative to radio waves but are definitely in the invisible range. Compared to visible light, their wavelength is larger, but option D specifies &#8216;small wavelength in the invisible range&#8217;, which is correct relative to, say, radio waves or considering the typical options comparing &#8216;visible&#8217; vs &#8216;invisible&#8217; and relative wavelength size.<br \/>\n<\/section>\n<section id=\"pyq-key-points\">\n&#8211; Microwaves are part of the electromagnetic spectrum.<br \/>\n&#8211; They are invisible to humans.<br \/>\n&#8211; The wavelengths are typically in the centimeter range.<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">\nMicrowave ovens commonly operate at a frequency of 2.45 GHz, which corresponds to a wavelength of approximately 12.2 cm.
