Re: light

1/2 Magnetic field, 1/2 Electric field - both alternating.
or
photons or quanta
or
wave packet
or
energy

A short, incomplete list...
1) Exhibits both wave and particle properties
-reflection
-refraction
-dispersion
-polarization
-scattering
-interferrence
-diffraction
2) Maxwell's equations
3) Speed is constant: c=l*f, where l=wavelength and f=frequency.

From the electromagnetic point of view, light is an oscillating magnetic field that creates an oscillating electric field, that creates an oscillating magnetic field, etc. This is called "propogation".
