Hello! Please help me with this question. I'm currently studying Light and Geometric Optics and have become quite confused. When looking at diagrams of mirrors, and light relfection into eyes, why is it that eyes only see things when tracing the light in straight lines? For example, if an apple were placed in front of a mirror, light rays would reflect off the apple and hit the mirror, thus reflecting in parallel lines that are percieved in our eyes. However, our eyes trace this light back into the mirror as though it came from the other side of the mirror. Why do our eyes see in straight lines and trace the light back into the mirror? And with diffuse reflection, the light is just scattered, yet we can still see the object. So, why is it that we can only see perfect relfected images if the light rays are parallel to one another? Please help!
