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. Image gallery ...

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 ...

Discovered more than a century ago, the electromagnetic spectrum is the basis on which our universe operates. Without it we wouldn’t be able to see, stars wouldn’t shine, and life would not exist.

And the shortest light waves are gamma rays. By understanding the electromagnetic spectrum, scientist can use it to explore the universe. For more information about light and color, check out the ...

Light with the longest wavelengths – millimetres, ... More on Electromagnetic spectrum. Physics Solving the 250-year-old puzzle of how static electricity works. Features. Environment ...

Gamma rays have the shortest wavelengths. They are produced by nuclear reactions and are used to treat cancer. Understanding the electromagnetic spectrum is important because it allows us to see and ...

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.

For thousands of years, humans were looking up at the star-studded night sky using just their eyes sensitive to the optical wavelength of the electromagnetic spectrum.The first telescopes ...

A: The Sun emits light in virtually every part of the electromagnetic spectrum, albeit some more than others. The sunlight that we see — aptly named visible light — falls into only a very ...

Learn about the electromagnetic spectrum, the order of the waves, their uses and dangers with this guide for KS3 physics students aged 11-14 from BBC Bitesize.
