The experiment confirmed that the device was able to transform the
light waves in the range of frequencies that would have been absorbed by the optical filter, then completely reverse the process as the
light wave exited the filter, making it look as though the laser pulse had propagated through a non-absorbing medium.
Due to the nature of this interaction, engineers and scientists have long known that in order to reverse the process and make an object "invisible," the color of
light waves hitting the object has to be manipulated.
When viewing an object, what you are really seeing is the way in which it modifies the energy of the
light waves that interact with it.
After a brief calibration, the mirror sent
light waves that passed back through the chicken again and combined to re-create the "5."

light wave propagating in vacuum at speed c is given by ([W.sub.0]c)/c = [W.sub.0][J/[m.sup.3]] where [W.sub.0] = [[epsilon].sub.0][E.sup.2.sub.0]/2 is the energy density of the
light wave and E is the amplitude of the strength of the alternate electrical field of the
light wave.
The researchers' goal was to design a structure that would predictably transform an incoming
light wave's shape.
The
light wave can make many trips around the ring before it is absorbed, but only frequencies of light that fit perfectly into the circumference of the ring can do so.
As a
light wave travels from one medium, such as air, into another, such as water, it follows Snell's law: When light refracts, it does so on the other side of an imagined line perpendicular to the water's surface.
A
light wave with a--amplitude creates a--reflected color.
In it, the budding theorist imagines what it would be like to ride on a
light wave.
Just as motion changes the pitch of a sound wave, it can change the length of a
light wave. Light emitted by an object moving away from Earth appears to have its wavelengths stretched, or lengthened, as indicated by its spectrum.
That means that the electric and magnetic fields that make up a
light wave vibrate only in particular directions.
