Question

Describe how the intensity of light changes with distance from a light source.

Answer 1

decreases

Step-by-step explanation:

The intensity of light is inversely proportional to the square of distance between the source and the observation point.

`Intensity \propto (1)/(distance^(2))`

So, as the distance increases by the factor of 2, then intensity becomes one fourth.

As the distance becomes half, the intensity becomes four times,
