After that the chapter talks about the vision and important things from this like waves of electromagnetic radiation, or our eyes and their respond to some of these waves an finally how our brain turns these energy wave sensations into colors. Hearing is another important point to understand as sound waves reach the ear with different frequency, amplitude and complexity. Finally the text explains others sense of the body like the touch, pain taste and smell to analyze the behavior in the body in different situation in our lives.
