The microwaves are large in wavelength compared to visible light, but still smaller than what?

• A. A meter
• B. A centimeter
• C. A kilometer
• D. A millimeter

Answer: (B)

Wavelength is a measure of how long a wave repeats, and it helps you compare different kinds of electromagnetic radiation. Visible light has very short wavelengths (about 400–700 nanometers). Microwaves have longer wavelengths, which is why they’re described as “large” compared to visible light. But even though they’re longer, they’re still quite small on everyday scales. A lot of microwave technology operates with wavelengths on the order of millimeters to centimeters, and the broad microwave range stays well below a meter in length. So, when we ask “microwaves are large compared to visible light, but still smaller than what,” the natural, general comparison is that they are smaller than a meter. That places them squarely in the micrometer-to-centimeter range, far below common human-scale distances like a meter or more. This is why the meter is the typical upper bound used to describe how microwaves fit into the larger spectrum.
