comment When does heat conduction become convection?
Thanks. I don't understand your comment about convection in a solid though. I understand that a solid does not possess the ability for convection. What I meant is: "The heat from the walls to the air can be transferred via convection (moving air) and/or conduction. Which one?".

comment Does a slide in a projector act as a diffuser?
I didn't snark at you? I just wanted to elaborate on my question. But you already provided a clear answer for which I thank you.

comment Does a slide in a projector act as a diffuser?
In fact the question is as follows: Do I have to raytrace from the light source through the lenses and slide to the screen, or can I assume that I can raytrace from the slide as starting point. So it the object plane the slide or is it the light source?
