How does the angle the light makes with the surface affect the results?
not really chemistry

It is at the greater angle (higher solar elevation) that the surface area receives the most energy because the rays are spread out less. ... The smaller the elevation angle (30°, 20°, 10°) the less energy received per square centimeter, because the rays spread out over a greater area.

Explanation:

correct me if I'm wrong

i think it is true since you can test the answer and can use observations to complete it.
