If the distance from a light source triples, how does light intensity change? the intensity will be 3x greater. the intensity will be 1/3 as much. the intensity will be 1/9 as much. the intensity will not change.

The intensity will be 1/9 as much.

Explanation:

The intensity of the light or any source is inversely related to the square of the distance.

Now according to the question the distance is increased by three times than,

Therefore,

Therefore the intensity will become 1/9 times to the initial intensity.
