PHYSICS: Today was the last of the applications of lenses. I love it when you get to see how physics crosses over into other disciplines of science – from physiology the other day with myopia and hyperopia and how lenses can help, to the applications today – how microscopes and telescopes work, and, ever important to know – why is sky blue!
Update on homework: the homework for thin lenses was incorrect. It should be: Pg. 508 – 512; 15 – 26 (Draw 24 – 26 to scale).
Speaking of lasts – LAST chapter test tomorrow!! What should you practice? Application of concepts, ray diagrams with mirrors and refraction through a transparent medium and lenses, and problems. Hey, here’s something to think about… can something really disappear into thin air? How??
