Duke Posted February 27, 2004 Share Posted February 27, 2004 This has been bugging me for a while now, but does anyone know why things look smaller when they are further away? I asked this about a year ago but I wasn't satisfied with the answers I was getting. Someone told me it has something to do with lenses. but I dont know whether thats true or not. Does anyone have a decent scientific reason as to why this occurs? Link to comment Share on other sites More sharing options...
JaKiri Posted February 27, 2004 Share Posted February 27, 2004 I shall answer in the medium of MSPaint. http://www.angelfire.com/space/mrl/furtheraway.JPG (The scales are slightly different on the pictures, obviously. The objects are the 'same' size) Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted February 28, 2004 Share Posted February 28, 2004 That was what I would say. Brilliant, yet my art teacher doesn't know. Link to comment Share on other sites More sharing options...
Atlantic Posted February 28, 2004 Share Posted February 28, 2004 Thats due to rectilinear propagation of light. Basically, the light spreads from an object in all diretions (grade 2) When you are close, your eyes capture more light, and therefore view more surface area of the object. When further away, your eyes capture less light rays from that object, and therefore the visual surface area is reduced. Link to comment Share on other sites More sharing options...
Sayonara Posted February 29, 2004 Share Posted February 29, 2004 That's no the best explanation, because it could just as easily produce the effect of perceiving a brighter or darker image. Link to comment Share on other sites More sharing options...
YT2095 Posted February 29, 2004 Share Posted February 29, 2004 probably not, but I understood it, and as for lighter / darker, you ARE joking right!?!? you`ll basicly see less reflected photons of that specific object as they scatter over distance and their angle of incidence will be less making the object apear smaller is all it is. nothing fancy Link to comment Share on other sites More sharing options...

ONE QUARTER RULE. VERY BASIC PHYSICS. you`ll basicly see less reflected photons of that specific object as they scatter over distance and their angle of incidence will be less making the object apear smaller is all it is. nothing fancy MrL already gave that answer in the first reply. Only with diagrams and flashing lights. Link to comment Share on other sites More sharing options...
YT2095 Posted February 29, 2004 Share Posted February 29, 2004 tell me what`s wrong with Atlantics post in the way that it will make things "darker" then? he even kicked of his sentnces with "Thats due to rectilinear propagation of light. Basically, the light spreads from an object in all diretions " and he`s bang on the nail Link to comment Share on other sites More sharing options...
Sayonara Posted February 29, 2004 Share Posted February 29, 2004 There's nothing wrong with the physics in the post. Can you not read? I said it was not good as an explanation, because it produces 2 different observable phenomena instead of just the one that he was trying to explain.

Intensity decreases as the area over which things are spread increases, duder. Link to comment Share on other sites More sharing options...

Seeing as all the information required to understand my post was in my post, I'd put it more in the "actual questions" category. I don't think responding to what you perceive as a "thinly veiled insult" with an actual insult is the way to go really. Link to comment Share on other sites More sharing options...
Duke Posted February 29, 2004 Author Share Posted February 29, 2004 That picture makes sense, i never really looked at it like that. Nicely explianed duderino. It beats the old "because it's further away" theory. Link to comment Share on other sites More sharing options...
