    i.e. plane wave front can do the same for sperical wavefront

    so i want to know what do electric field vectors look like for a spherical wave front

    ah okay, so the point source can be treated as the center of the sphere, and light is propagating in all directions away from this point? you want to know the electric field vectors it produces?

    intensity at surface of the sphere \[I = \frac{ S }{ 4\pi r^2 }\] Each square follows the law so intensity will change at each one like, I ...I/4....I/9

    Same applied for electric field E, as \[E = \frac{ Q }{ 4 \pi \epsilon_0 r^2 }\]

    Where source strength would be \[= \frac{ Q }{ \epsilon_0 }\]

    If you want vectors, and the nature of light, you want to be looking into maxwells equations, and to understand them, grasp the concepts of vector calculus, curl, divergence, grad, laplacian

    ok, but how do the electric field vectors look like on a wavefront at particular time?|dw:1361890945224:dw|
