Honors Physics conducted a lab investigation centering on mirrors, reflection and polarization. Plane mirrors were investigated to validate the law of reflection and the pattern of image formation was described. Students then worked with convex and concave mirrors to assess what types of images these mirrors could form. For polarization, students examined Malus’s law, which allows one to predict the intensity of light passing through a polarizing filter system based on the angle of the polarizer. Students found that light intensity decreases steadily as one polarizer is rotated with respect to a second, with maximum extinction occurring when the polarizers are at 90 degrees. The overall data supported Malus’s law, which further supports the model of light as a transverse wave.

Physical Science B and Physical Science E reviewed for Monday’s exam on sound and light. We walked through the chapter, reviewed study materials and answered any questions that still plagued folks. Starting Tuesday – Electricity!

Physics F and G began their discussion of light and reflection. We described the dual nature of light and then moved to the basics of reflection. Specular and diffuse reflection were contrasted and described based on the law of reflection. The, attention turned to plane mirrors and the formation of virtual images. On Monday, G Block will engage in a lab activity that will allow them to explore both plane and curved mirrors, while F Block begins to discuss how curved mirrors produce images.
