Tony Hanson · Answer 1

The intensity of a light in a surface follows the inverse square law formula which can be mathematically expressed as,

I = k/d²

where I is intensity, d is distance, and k is the proportionality constant. For us to increase the intensity, we should lower the distance from the source to the surface.
