Electromagnetic Spectrum


Lately in class, we have been reading about the electromagnetic spectrum. It is quite an impressive topic to learn about. The amount if different waves and light in our world is amazing, especially since we can only see such a small percentage of it. Besides visible light, there are radio waves, infrared, ultraviolet, x-rays, and gamma rays. All of those have their own different wavelength and frequency. Radio have the highest wavelength, but lowest frequencies. On the other hand, gamma rays have the shortest wavelength and highest frequency. From longest wavelength to shortest, the order is radio waves, radar, infrared, visible light, ultraviolet rays, x-rays, and then gamma rays. As you can see, the electromagnetic spectrum is quite fascinating.
