The sum of the emitted photons - say from an electric bulb - is called electromagnetic radiation. The emission from a laser is very strong directed, from a bulb it is much more spherical directed. So the radiation could be spherical, no matter would this be from a bulb or a star. score of rams game tonightWebBy the same line of reasoning, a converging spherical wavefront will collapse down to a perfect point image. Thus we may conclude that a perfect eye converts spherical expanding wavefronts into spherical collapsing wavefronts. If we require that an eye be well focused for distant objects, then the sphrerical wavefronts arriving at the eye will predicting winter northeast
