Visible light is just a small part of a continuum of electromagnetic radiation that extends from radio waves to gamma rays. Phenomena as diverse as radio waves used to transmit information, microwaves used to cook food, and x rays used for medical...

This extends over the range of wavelengths from 10–12 cm to 1010 cm The shortest wavelengths are generated by cosmic and X-rays and the longer wavelengths are associated with power generation and microwaves. Ultraviolet, visible and infrared...

The electromagnetic (EM) spectrum is the range of all possible electromagnetic radiation. The "electromagnetic spectrum" (usually just spectrum) of an object is the characteristic distribution of electromagnetic radiation from that object. The...

In all the time I've been doing this column, I've never discussed how the complete electromagnetic spectrum was originally mapped out. So, I'll do it now. Spectroscopists should understand that all regions of the electromagnetic spectrum are used in some form of spectroscopy. ...

As technology plays an increasingly vital role on the battlefield, a new military occupational specialty has emerged. The 25E electromagnetic spectrum manager is "responsible for assigning the electromagnetic spectrum across the battlefield," said Stanley Oliver, electromagnetic spectrum course chief. The MOS...

A new NASA space telescope will give scientists a peek at some of the most energetic objects and events in the universe. The new Gamma-ray Large Area Space Telescope to be launched next spring doesn't see visible light like our eyes, but gamma rays, the...

For a quarter century, chefs at pricey steakhouses have been searing meat on burners that cook with infrared energy. Now the high-temperature technology may be coming to a backyard barbecue near you.With the expiration of a key patent, major gas grill manufacturers, including market leader...

Discusses the phenomenon of light. Describes how Light reflects off of certain colors to allow colors to be seen. Questions what is light spectra, who found light spectra, how is light spectra used to classify stars, how is light spectra measured, and what is used to measure light spectra?
