The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. Longer wavelengths with lower frequencies make up the radio spectrum. Shorter wavelengths with higher frequencies make up the optical spectrum. The portion of the spectrum that we can see ...

some of the wavelengths of the electromagnetic spectrum and the danger of some of the radiation, only the visible light spectrum will be studied in the activities that follow. Several different methods for displaying the visible spectrum will be presented. Some of the demonstrations will involve sunlight, but a flood or spotlight may be ...

spectrum. The electromagnetic spectrum is summarized in the diagram in Figure 1.2. •On the far left of the diagram are radio waves, which include microwaves. They have the longest wavelengths and lowest frequencies of all electromagnetic waves. They also have the least amount of energy. •On the far right are X rays and gamma rays. The have ...

the order they fit into the electromagnetic spectrum All of these are "electromagnetic waves". This means that although they appear to be very different, in fact they're all made of the same kind of vibrations - but at different . All electromagnetic waves travel at the same speed - 300,000,000 metres per second, which is the speed of light.

The Electromagnetic Spectrum 2 CESAR’s Booklet The electromagnetic spectrum The colours of light You have surely seen a rainbow, and you are probably familiar with the explanation to this phenomenon: In very basic terms, sunlight is refracted as it gets through water droplets suspended in the Earth’s atmosphere.

of the continuous range of electromagnetic waves that form the electro-magnetic spectrum. On one end of the spectrum are radio waves, with wavelengths that can be as large as mountains. On the other end of the spectrum are gamma rays, with wavelengths as small as atomic nuclei. Frequency is a measure of the number of wave crests passing by a given
