So it is possible, that it will be strange to picture. And other point is the point of reflection on the surface of the pond, which by reflection on the water is the reflection that occurs at the contact surface between water and air of Maxwell's equations, which describe the journey of light at the surface of the connector. And when light interacts with them its wave nature is significant. light is not simply refracted or reflected at the drop surface. instead, its waves are scattered or diffracted in all directions to produce a wildly oscillating ringed pattern right around.
