Today a lesson and as assignment on the bending of light (refraction).
Today you saw Jay Dixon speak in the Crusader Arts Centre.
WE looked at the working parts of the human eye and what they do. We also looked at near-sightedness and far-sightedness. We looked at how glasses (lens) correct our vision.
Today a pHet lesson on additive and subtractive theory of light.
WE had a quiz on light and mirrors today and started on the theory of light and colour.
We looked at how to find an image in a plane mirror. You should know how to do this.
Also we looked at uses for the 3 types of mirrors: plane, concave and convex. Today you did ray drawings that were handed in for marks. WE also compared the 3 types of mirrors: plane, convex and concave . Handout.
Today we learned how to use the ray boxes to draw actual ray diagrams.
We also took a note on what light does when it hits an object: 1) is absorbed, 2) reflects 3) goes through. Today we learned how to draw ray drawings and practised measuring angles with a protractor. We also did some review on what we've learned so far.
Today we studied sources of light and the EMR spectrum. We worked on seatwork questions: p. 429 # 1, 2, 5 p[. 433 # 2,3 p. 490 # 1,2,3 and p. 42 #4
