No, Henry is correct. Power recieved / power transmitted is
proportional to 1 / (range**4).


My feedback was offered in the interest of careful wording.  It's easy
to have a perfectly accurate thought, but then put that thought into
words that are completely inaccurate.


It's even easier to express an inaccurate thought, and it's often better not to express a thought..
