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

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
