Question

If light intensity obeyed an inverse square law you would expect to find the intensity of light to decrease as the square of the distance increases?
True or false

Answer 1

this is a true statement

Answer 2

Inverse square law: $\frac{I_{2} }{I_{1}}= (\frac{d{2} }{d_{1}})^2$
where 
$I_{1}$ is the intensity at distance 1
$I_{2}$ is the intensity at distance 2
$d_{1}$ is distance 1
$d_{2}$ is distance 2

The inverse squared law state that intensity decreases in inverse proportion to the distance squared. So if light obeyed that rule, it will decreases its intensity as the square of the distance increases.

We can conclude that the correct answer is: true.
