[a]1. Homework Statement [/b]

How does the distance from a point source of light affect the visibility of that light from the said source?

This is a bit tricky without sub points, but here goes:

I

where:

I=intensity d

[c]3. The Attempt at a Solution [/b]

By using the ISL formula above, I plan to find the intensity of light at predefined intervals (i.e. every 10 cm) by substituting variables in the equation. After which, I will use a voltmeter and CdS cell to verify my calculations. I'm pretty sure I'm doing everything right, but some suggestions would be nice.
