Is there a linear relationship between the two?
I ask because I'm investigating the effect of a different variable on the power output of a solar panel, and intensity is meant to be one of my control variables.
However due to insufficient apparatus I could not control the intensity of light.
For example, say I wanted to control the intensity at 40 lx. However in one of my tests the intensity of light was 120 lx. If I were to divide its power output by 3, would I get the (approximately) same value as I would if the intensity were truly 40 lx?
If any clarification is needed let me know. Thanks in advance.
