I can imagine shining the light right in your eyes would be visible, but if you shone the light on your forearm, would you be able to see it? Yes, you would, but might someone please qualify this assertion if needed?
If you shone a plain exposed light bulb, would you be able to
see visually perceive in any fashion the floor/walls/ceiling? (Again, assume that this room's interior surfaces absorb light to a similar degree that the anechoic chamber absorbs sound.)
Consider a (reflecting/opaque) object placed nearly (but not exactly) at opposition to this light bulb (from the reference of the viewer--think Solar System astronomy here). Would there be substantial glare from the light bulb such that the remote object could not be seen?
