You should be reading Chapters 16-19, and 26;

Light colors, mirrors and lenses.

Final extra credit- It is a lot of work so start early

for 15 points on final exam you must define all vocabulary on the chapter summary pages chapters 1-26, you must also write a question for each of the key concepts so that the concept is the answer to the question. I would start at least with the chapters 14 and 15 seeing that we are studying them right now!

Example- Pg 335 first concept reads " the temperature of a gas is proportional to the average kinetic energy of its particles." The question could read "what is the relationship between the temperature of a gas and the average kinetic energy of the gas?" then you would write the answer to the question. This way if you handed this to some one they could pick and choose questions to ask you and have the answer right there to check your work.
