When I placed a lamp next to a mirror where I can see “two lamps”, does that double the light output? I know all the light that would have been wasted on the wall is now being returned so is it a yes?

This reminds me of a great demonstration of how directional antennas focus radio waves in one direction: https://youtu.be/lslHtCUSfN4

That was a cool vid- I don’t know much about antennas, so that was a fascinating watch. Thanks!
