Inverse Square Law & Light Intensity in Photosynthesis - GCSE Biology

🦊 In this GCSE Biology video, we discuss the inverse square law in the context of photosynthesis, explaining that light intensity is inversely proportional to the square of the distance from a light source. As the distance between a plant and the light source increases, the brightness of light that the plant receives decreases. This relationship is non-linear, meaning that if the distance is doubled, the light intensity reaching the plant reduces to a quarter of its initial value. Understanding this inverse square law is important in the study of photosynthesis, although it's not necessary to memorize the exact equation. Remembering the concept that increasing distance drastically reduces light intensity is key for understanding this aspect of plant biology.
