Understanding the Inverse Square Law in Regards to Light Intensity and Photosynthesis

The video tutorial explains how light intensity affects the rate of photosynthesis, highlighting that it is directly proportional to light intensity. It introduces the concept of direct proportion, where both variables increase at the same rate, and illustrates this with a graph. The tutorial also covers the inverse square law, explaining that light intensity decreases with the square of the distance from the light source. This means doubling the distance reduces light intensity to a quarter. The video concludes with a recap of these concepts, emphasizing the relationship between light intensity, distance, and photosynthesis.

Describe the inverse square law in relation to light intensity and distance.

How does the rate of photosynthesis change when the distance from the light source is halved?
