Re: naive ideas: Light



Hi,
Just one point about this item: what about things that emit light and
are thus seen by this light rather than light that is shone on it?

Thank

Light:

2. An object is "seen" because light shines on it. Light is a necessary

I think this is basically correct. Light is a necessary condition for my
eye to see an object. Light must be shining on the object that I am trying
to see. For if it were not, there would be no scattering of the light into
my eye.
