Today in Period 2 we learned about the phenomenon of total internal reflection and the concept of the critical angle. We saw a couple of demonstrations about the critical angle and total internal reflection and learned about how fibre optics work. This was covered on slides 57-62. Students then worked on Part C of the Refraction Practice Problems. I will go over this tomorrow.
In Period 4, I was away, but the sub should have started to look at optics and lenses. Students learned about the different types of lenses as well as how find images in the different types of lenses mathematically. This was covered on slides 64-77. Reminder that tomorrow students will be writing the quiz on the speed of light, magnification and the mirror equation. We will finish the notes on the lens equation tomorrow and students will then get into Homework 3.5
