Born Hunter 17,775 Posted August 3, 2011 Report Share Posted August 3, 2011 no i wasnt being sarcastic mate, just looked on wiki before you had posted it. so the umbra is the part of the field that we cant see at all? Yeh, thats the dark part of the shadow, where all light from the source is blocked out. The penumbra and antumbra are just parts of a shadow where the light source is only partially blocked out. If you shine your lamp at a pool cue from a good distance in a dark room you should see the 3 distinct parts of a shadow.... Quote Link to post
Guest dances Posted August 3, 2011 Report Share Posted August 3, 2011 thanks for that mate, so when the dogs catch out of the beem it would have to be the other 2 and not actually the umbra? Quote Link to post

Guest dances Posted August 3, 2011 Report Share Posted August 3, 2011 this is a very crude diagram but will hopefully get my point across, the red crosses are the prenumbra which in theory if the dog caught there there would still be a slight amount of light should it be minimal Quote Link to post
Born Hunter 17,775 Posted August 3, 2011 Report Share Posted August 3, 2011 (edited) Ermmm, no. The penumbra is casued by the shadow of what ever your shining the lamp at, so out of the beam isnt strictly the shadow of the lamp but the shadow of the earth from the sun. Its getting abit complicated now. You used the term correctly in your write up if thats what your worried about. I wasnt correcting you pal Edited August 3, 2011 by Born Hunter Quote Link to post
