    Re: light

    Depends on who you ask...
    1/2 Magnetic field, 1/2 Electric field - both alternating.
    photons or quanta
    wave packet

    A short, incomplete list...
    1) Exhibits both wave and particle properties
    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".
