Final answer:
The EM waves listed from shortest to longest wavelength are gamma rays, X-rays, ultraviolet, visible light, infrared, microwaves, and radio waves. Gamma rays have the shortest wavelengths, while radio waves have the longest.
Step-by-step explanation:
The electromagnetic (EM) spectrum encompasses different types of EM waves, which can be listed from shortest to longest wavelength as follows: gamma rays, X-rays, ultraviolet (UV) light, visible light, infrared (IR) radiation, microwaves, and radio waves.
Gamma rays have the shortest wavelengths, sometimes less than 0.01 nanometers, and carry a significant amount of energy making them potentially dangerous to living tissue. At the other end of the spectrum, radio waves can have wavelengths as long as several kilometers. In increasing order of wavelength and decreasing order of frequency and energy, EM waves include gamma rays, X-rays, ultraviolet light, visible light, infrared radiation, microwaves, and ultimately, radio waves.
