👉 Photopic is a concept in physics that describes the phenomenon of light being able to pass through a transparent material without any change in its intensity or color. It involves the absorption, reflection, and transmission of light by matter, which allows it to be seen as white light rather than black by an object. This property is essential for most biological processes, including photosynthesis, where plants use sunlight to convert carbon dioxide and water into glucose through a process called photosynthesis.
