The Electromagnetic Spectrum is a family of waves identified by their frequency/wavelength where each member has practical applications. Part of Science Vibrations and waves ...

Although the wavelength and frequency of these waves are all different, all regions of the electromagnetic spectrum transfer energy. Another thing that they have in common is that they all travel ...

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.

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 ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz.

Higher up the electromagnetic spectrum, well beyond those frequencies used by mobile phones, there are clear health risks from extended exposure.
