Question

What is the electromagnetic spectrum? (from largest to smallest wavelength)

A) X-rays, Ultraviolet, Infrared, Visible, Microwave, Radio
B) Radio, Microwave, Visible, Infrared, Ultraviolet, X-rays
C) Infrared, Microwave, Visible, Ultraviolet, X-rays, Radio
D) Visible, Ultraviolet, Infrared, X-rays, Microwave, Radio

Answer 1

The electromagnetic spectrum is the range of all electromagnetic radiation, ordered by wavelength from largest to smallest as follows: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Step-by-step explanation:

The Electromagnetic Spectrum

The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency or wavelength. These waves include, from the longest wavelength to the shortest: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays, and gamma rays.

Each category of electromagnetic radiation has its unique place on the spectrum and can be characterized by its wavelength, frequency, and the amount of energy the waves carry. The correct order from largest to smallest wavelength is: radio, microwave, infrared, visible, ultraviolet, X-rays, gamma rays.
