    1. The problem statement, all variables and given/known data
    This is not an assigned question, I am very confused regarding how light travels. are all of the following parts of my explanation correct?

    Consider a charge which undergoes an acceleration for a finite amount of time. This results in an electromagnetic pulse that propagates through space. The way this pulse continues throughout the electric field is via the mutual induction of electric and magnetic fields. Therefore a charge experiencing oscillatory motion will produce these pulses at a certain rate, which determines which color we see (the pulses reach us at a certain rate, which is the frequency of the radiation).
    2. Relevant equations
    integral around a closed loop Eds = - dmagneticFlux/dt
    integral around a closed loop Bds = mu-nought * epsilon-nought*delectricFlux/dt

    3. The attempt at a solution
    explained above

    Yes, that happens in principle. :)
