how the wave equation arises out of Maxwell's Equations? please write as simple as possible so i can get it through my head.

A changing electrical field generates a magnetic field in a plane at a 90 degree angle to the plane of the electrical field. The energy of the magnetic field drains energy from the electrical field.

The two fields keep feeding back onto the other in a self-perpetuating manner. The waves propogate forward at the speed of light as measured by an observer.

Maxwells four equations related to Electric fields and magnetic fields.Maxwell discovered that in the world of magnetic field(measured in units of time ) and electric field(measured inunits of inverse distance),found that the Ratio of these moving fields yielded a constant which he described as the speed of light square. Hence tied the motion of light to an electric field and magentic field which later was coined electromagnetic wave.However it never meant that light was magnetic or electric. Something which is still not understood today
All it indicated was that the interaction of a movingElectric field and a Magnetic field was taking place at the Speed of light.
Wave Equations were developed out classical physics by Schroedinger In 1926 and later Marshak solved the time independant schoedinger equation. .These related to the propagation and motion of energies per unit distance in the form of oscilations,obeying the rules of a wave.
Later Paul Dirac formulated the Relativistc Wave equation in 1928.

i don't know any of Maxwell equations but if u can explain the phenomenon i would be more than happy to explain the equation

Attached is a great web page that breaks it down into easy steps. I assume you mean the most famous of his equations... light <> electromagnetism...

in water or any medium, v=c/n, the place n relies upon on ? and µ. it extremely is the undemanding definition, yet in extra stepped forward ranges, ? and µ are frequency based, so diverse colorations of sunshine could have diverse speeds. c is a persevering with in vacuum, and velocity of sunshine is no longer c in a medium.

Its easier to go through this proff on your own:
