1. The problem statement, all variables and given/known data n/a 2. Relevant equations n/a 3. The attempt at a solution n/a In my physics class we are learning about the EM radiation/wave nature of light/wave optics / image formation by mirrors and lenses, and I had a general question that was not really discussed in the textbook. I understand the "technical aspects" such as understanding the equations and concepts/ how images are formed with mirrors and lenses etc, but what is exactly going on with the objects? How do we even see things in the first place? seems like a dumb question, but i'm not sure of the answer for example, suppose we have an object and a convex mirror for the ray diagram we would draw rays coming from the object and reflecting off the mirror, forming an image. are these rays coming from the object? where do these rays come from? is the answer that the object absorbs solar radiation but doesn't absorb all the light, then the light that isn't absorbed by the object travels to the mirror and is reflected off? thank you!
