There are seven groups of the electromagnetic spectrum. To the left of the electromagnetic spectrum are radio waves, the lowest frequency form of radiation with the longest wavelengths.

Parts of the electromagnetic spectrum invisible to human eyes reveal a vast amount of information about the universe, but it took a long time for astronomers to learn how to view it.

By understanding the electromagnetic spectrum, scientist can use it to explore the universe. For more information about light and color, check out the Science Trek website.

Each region of the electromagnetic (EM) spectrum has a range of wavelengths associated with it. Radio waves have the longest wavelengths and gamma rays have the shortest wavelengths.

The electromagnetic spectrum has many types of light waves. It includes radio waves, microwaves, infrared light, visible light, ultraviolet, X-rays, and gamma rays. Each type of light has a different ...

Each region of the electromagnetic (EM) spectrum has a range of wavelengths associated with it. Radio waves have the longest wavelengths and gamma rays have the shortest wavelengths.

Light with the longest wavelengths – millimetres, metres or even kilometres across – takes the form of radio waves. On the other side of the spectrum, light with wavelengths slightly shorter ...

Violet has the shortest wavelength that people can see, while red has the longest. At both ends of the visible spectrum, there are wavelengths that people cannot see, such as ultraviolet and ...

Looking at the Sun in this portion of the electromagnetic spectrum highlights its delicate — and extremely hot — outer atmosphere, the corona.

Similar to the visible light spectrum, which ranges from violet (the shortest visible-light wavelength) to red (longest wavelength), infrared radiation has its own range of wavelengths.

A team of researchers from George Washington University has devised a new layered solar panel that can absorb light from a wider range of the spectrum pushing the efficiency as high as 44.5 percent.

For a look at the jobs that remain posted for the longest (and the shortest) amount of time, check out our slideshow below, made up of a list of the most fleeting and longest-lingering positions ...
