The process through which light enters the eye and is converted by retinal cells into electrical signals that can be processed by the brain is called 4) transduction.
In the field of biology, transduction can be described as the process by which the trapped light in the retina can be interpreted by the brain through the electrical signals of the nerve impulses.
In the retina, rods and cones are present which are responsible for the trapping of light. The light trapped in these parts of the brain is converted into electrical signals by the nerves present in the eye. These electrical signals are traveled to the brain through the optic nerves. The brain interprets these signals and produces vision.
