The beauty of a coral reef, the warm radiance of sunshine, the sting of sunburn, the X-ray revealing a broken bone, even microwave popcorn—all are brought to us by electromagnetic waves.
Even more intriguing is that all of these widely varied phenomena are different manifestations of the same thing—electromagnetic waves.
It is worth noting at the outset that the general phenomenon of electromagnetic waves was predicted by theory before it was realized that light is a form of electromagnetic wave. Such a theoretical prediction followed by experimental verification is an indication of the power of science in general, and physics in particular.

The speed of propagation c can be the speed of sound *or* the speed of light and radio waves. The notation "eV" stands for electron-volts, a common unit of energy measure in atomic physics.
The prediction was made by James Clerk Maxwell in the mid-19th century when he formulated a single theory combining all the electric and magnetic effects known by scientists at that time. The underlying connections and unity of physics allow certain great minds to solve puzzles without having all the pieces. Undergraduate level physics, chemistry, organic chemistry and biology are presented by this course as a unified whole within a spiraling curriculum. WikiPremed offers the customers of our publications or our teaching services no guarantees regarding eventual performance on the MCAT. Sound creates pressure variations (waves) in matter, such as air or water, or your eardrum.
The radio in your car receives the radio waves, decodes the information, and uses a speaker to change it back into a sound wave, bringing sweet music to your ears.


The prediction of electromagnetic waves is one of the most spectacular examples of this power.
Conversely, radio waves are electromagnetic waves, **like visible light, infrared, ultraviolet, X-rays, and gamma rays. The work of WikiPremed is published under a Creative Commons Attribution Share Alike 3.0 License.
EM waves don’t need a medium in which to propagate; they can travel through a vacuum, such as outer space.
