YES, that is what I said.

"There is a law called "the inverse square law." Essentially this means that if you take an object and move it closer to you by say 1/2 as close then its size as you see it becomes 4 times larger. If you move it away, say 2 times as far, its size as you see it becomes 1/4 as large. This works for images, sounds and for radio signals."

... but I could have been more specific about the linear dimensions being twice or 1/2 the amount they were before the object was moved.
A light or a radio signal works like the size of a linear object.
1/4 as weak or 4 times as strong as the source or receiver is moved twice as far away or half as close.
I need my "wordy" nephew to proof read my wording.
