Electromagnetic Spectrum

Electromagnetic radiation can be described in terms of a stream of photons, which are massless particles each traveling in a wave-like pattern and moving at the speed of light. Radio waves, light, x-rays, and other parts of the electromagnetic spectrum are all electromagnetic radiation. This article, Measuring the Electromagnetic Spectrum instructs you about the different types of radiation in the electromagnetic spectrum. Definitions are provided for many terms used in the descriptions for better understanding of this subject. Color illustrations also accompany many of the terms.

Electromagnetic Spectrum

Students will learn about the nine levels of frequency and wavelengths included in the electromagnetic spectrum by studying this chart, which allows students to click on any of the nine levels for additional information. Each level contains an explanation of how the frequency can be used, along with statistics for the frequency, wavelengths, and quantum energies. Also included is a calculator for wavelengths and frequency, which provides an opportunity for students to experiment with the formulas.

The Electromagnetic Spectrum

Many devices you probably use every day are made possible by the electromagnetic spectrum. Some examples of these useful items are radios, cell phones, and microwave ovens. The scientists at the National Aeronautics and Space Administration, or NASA, invite you to visit their colorful, informative web site to uncover the facts about these essential, yet sometimes invisible, waves. The range of the spectrum covered includes radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. You'll gain knowledge about the discoveries of scientists James Clerk Maxwell and Heinrich Hertz. Learn how cool these types of waves can be.

Ultraviolet and Infrared Photography Summarized

Andrew Davidazy of the School of Photographic Arts and Sciences presents information about ultraviolet and infrared photography. Information is also linked to the Imaging and Photographic Technology Department of Rochester Institute. Learn about the proper use of lights, filters, film, and exposure techniques when applied to the four basic methods of photographing the invisible spectrums of ultraviolet and infrared light. Useful information to art historians is produced by ultraviolet and infrared photography.
