Answer:
Light Source: Objects are visible because they emit light or reflect light.
Eyes: The eyes receive light.
Refraction: The eyes focus the incoming light.
Retina: Light-sensitive cells in the retina convert light into electrical signals.
Optic Nerve: Electrical signals travel to the brain via the optic nerve.
Brain: The brain processes these signals to create the image of what we see.
We see objects because our eyes capture and send signals to the brain when light interacts with those objects.
