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. |

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? |

Mechanical work to required battery power So I can safely go from the Jouls needed to the ones generated by the battery. I factored in losses due to friction, but a general efficiency rule regarding batteries is hard to find. |
