For today's lab practicum, you were asked to experimentally determine the index of refraction of several unknown substances.

Today we talked about total internal reflection, how to determine if TIR was possible, how to find the critical angle, and some applications. Homework is p. 834 #6,7 (Concept questions) and p. 836 #26-31.
Today we talked about refraction and Snell's Law. Homework is p. 834 Focus problems 1,5 p. 835 #1-3, 9, 10, 12, 16
Monday and Tuesday we worked on an online simulation to better understand refraction and to develop an understanding of Snell's Law and total internal reflection.
Today we finished up any work that we had for plane and spherical mirrors. Tomorrow is a quiz on spherical mirrors. Make sure you know the law of reflection, properties of concave and convex mirrors, how to use ray diagrams to locate an image, and how to use the mirror and magnification equations.
Ray Tracing Assignment KEY Spherical Mirror Assignment KEY #19-26 only Today we learned the mirror equation and magnification equation for curved mirrors. Homework is p. 792 #4,7 and p. 793 #3,5,6,19-26.
Today we used the technique of ray tracing to locate the image formed in concave and convex mirrors. The ray tracing packet is due tomorrow at the beginning of the period.
On Friday we will have a quiz covering the two labs that we did - the lightbox lab and the mirror lab. Make sure you understand the law of reflection, how to draw a normal line, be able to identify the angle of incidence and the angle of reflection, and measure them. Be able to identify where an image will form in a plane mirror using sight lines and angles like you did in the mirror lab.
Now that you understand some basic things about light and reflection, you're doing another lab to determine where the image is formed in a mirror.
Today we completed the ray tracing lab. Each person should have 4 traces (plane mirror, concave mirror, convex mirror, and 2 plane mirrors).
