Light waves wiggle strictly perpendicular to their path

HERE’S THE INTERESTING PART

While sound shoves things straight forward, light is infinitely more dramatic. An electromagnetic wave propagates forward while its internal electric and magnetic fields furiously vibrate up, down, and side-to-side, strictly perpendicular to the actual direction it is traveling. It literally wiggles its way across the universe.
