Compare the intensity of light 2 meters away from a lit match to the intensity 6 meters away from the match.

The ratio of intensity to distance is an inverse square law so if you increase the distance by 3 times, the intensity will reduce by 3 2 times
so the intensity will be 9 times less.

The intensity of light from a lit match decreases as you move further away due to the inverse square law. At 2 meters, the intensity is greater than at 6 meters by a factor of 9, with the intensity at 6 meters being 9 1 ​ of that at 2 meters. This demonstrates how light diminishes with distance from the source.
