Image illustrates different wavelengths with creatures and objects in the ocean
It can be difficult in our everyday lives to appreciate the extraordinary range of wavelengths in the electromagnetic spectrum. Electromagnetic radiation—from radio waves to visible light to x-rays—rises and falls as it travels through space, like waves rippling across the ocean.
The length of these waves—measured from peak to peak or valley to valley—helps define their properties and potential uses.
This infographic uses ocean creatures and objects to express these different wavelengths, which can actually stretch to sizes both larger and smaller than this image conveys. Many of these objects, including the 30-meter blue whale or the 2-centimeter pygmy seahorse, can be easily seen with the naked eye.
But scientists and students must use microscopes and similar devices to see the objects in the middle of the spectrum, including algae and viruses. At the right end of the spectrum, however, much more sophisticated instruments are required.
Brookhaven Lab specializes in exploring materials on the nanoscale, spanning just billionths of a meter. To reveal structural details the size of DNA, we use powerful x-rays produced at the National Synchrotron Light Source II, precise electron microscopes at the Center for Functional Nanomaterials, and a host of other sensitive instruments and techniques.
Investigating materials at that scale—from lithium-ion batteries to cell-building proteins—allows fundamental discoveries that can revolutionize our understanding of biology, energy technology, and even the cosmos.
In fact, Brookhaven Lab scientists use the Relativistic Heavy Ion Collider to explore subatomic phenomena spanning just millionths of a billionth of a meter—too small to fit onto this graphic of the electromagnetic spectrum produced by Media & Communications and Creative Resources' designer Tiffany Bowman and science writer Justin Eure, in collaboration with our researchers.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
