Physics of vision

The physics of vision involves light, our eyes, and how we perceive images. Light travels in waves and enters the eye through the cornea, then passes through the pupil and lens, which focuses it onto the retina at the back of the eye. Photoreceptor cells in the retina convert light into electrical signals. These signals travel via the optic nerve to the brain, where they are interpreted as images. Factors like color, brightness, and motion depend on the properties of light waves, while our brain's interpretation creates the experience of seeing the world around us.
