But if you look closely (so to speak), you would see that the photons of light are first absorbed by the electrons of the ball, and then re emitted, and then they reach your eye. But when they reach your eye, how does your brain actually 'see' it? There are many many factors. Because of the 3D shape of the object, the amount of photons falling on each part of the object is not same. So depending upon from where most photons are coming, our brain creates an spacial 2D intensity image.
When light interacts with an object, its photons are absorbed by the object's electrons and then re-emitted. These re-emitted photons eventually reach your eye, but the process of how your brain interprets this information is complex. The three-dimensional shape of the object causes variations in the number of photons striking different parts of its surface. Based on the distribution of these photons, your brain constructs a two-dimensional intensity map, which helps you perceive the object's spatial characteristics.
When examining the process, it becomes apparent that photons of light are initially absorbed by the electrons of the object and then re-emitted, ultimately reaching your eye. Once the photons reach your eye, the brain interprets this information in a complex manner. Various factors influence this interpretation, such as the three-dimensional shape of the object, which affects the distribution of photons across its surface. Consequently, the brain constructs a two-dimensional intensity image based on the direction from which the majority of the photons originate.
If you look at the process, you see that photons of light are first absorbed by the object's electrons and then re-emitted, finally reaching your eye. After the photons reach your eye, the brain processes this information in a complicated way. This interpretation is affected by several factors, including the three-dimensional geometry of the object, which influences the photon distribution on the surface. Thus, the brain builds a two-dimensional intensity image according to the direction of the majority of the photons.
When you look at the process, you see that photons of light are first absorbed by the electrons of the object and then re-emitted, and finally your eye. When the photons get to your eye, the brain processes this information in a complicated way. This interpretation is affected by several factors, including the three-dimensional shape of the object, which determines the spatial distribution of photons on its surface. Therefore, the brain builds a two-dimensional intensity image from the direction of the most photons.
