Hi there. This is my firs tpost so go easy on me. My question is how come we can see the entire face of a distant object. Let me take the sun as an example. When I look at it, i pressume what i can see is the entire face of it that is pointed towards me, but what I dont understand is how. As the light that is eminating from the face i can see also is reaching to my left, to my right above and below me. The way I am picturing it in my mind is if a pebble is dropped in a pool of water, the further the ripple goes, the wider it gets. Now if I were to place a stake in the water 100m away, the stick would only receive a proportion of the ripple that is as wide of the stick. So in effect a small section of the orignal wave. I assume that the same is also true for light leaving the sun? So how come I can see the entire face?
