minus-squareRedjardlinkfedilinkEnglish3•9 months agoThe easy to show part was the second sentence of my comment. This is really useful physics trivia, because the basic truth is easy to show from a simple law, but the detailed explanations go quite in-depth. With lenses, you trade bewteen angular accuracy and light density. For a challenge, try it with LEDs. Where do you find the source “temperature”, you can get from focusing an LEDs light?
