The complete range of electromagnetic waves placed in order of increasing frequency is called?

• A. Electromagnetic spectrum
• B. Visible light
• C. Electromagnetic radiation
• D. Translucent

Answer: (A)

The complete range of electromagnetic waves placed in order of increasing frequency is called the electromagnetic spectrum. This spectrum collects all electromagnetic waves together and lines them up from lowest to highest frequency (which also means from longest to shortest wavelength). Understanding this helps: radio waves are at the low end, then microwaves, infrared, visible light, ultraviolet, X-rays, and finally gamma rays at the high end. Visible light is just a small slice of the whole spectrum. Electromagnetic radiation is a broader term for EM waves in general, but the term for the full ordered range is the electromagnetic spectrum.
