    Question :-

    Why fire when burnt gives light ?

    Theory :-  Visible light is an EM Wave i.e. a result of transverse electric and magnetic field.
    That is the reason, its dark in space and Earth has visibility from EM waves.

    Than why when we burn a matchstick, it burns giving visible light? Magnetic field is though from Earth's own Magnetic field, Where from transverse electric fields come to support flow of EM wave?
