Light from a lamp is shining on a surface. how can you increase the intensity of the light on the surface?

1 answer:

4 0

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.
