OPTICS TEST #1 OUTLINE:
Test date: Friday, March 4 2011

  1. Calculations:
    a. Pinhole camera
    b. Index of refraction using n = c/v and Snell’s Law equation
    c. Convex Lens calculation (using 1/f = 1/di + 1/do)
  2. Ray diagrams:
    a. Plane (flat) mirror
    b. Concave mirrors
    c. Convex lenses, producing both real and virtual images
  3. Types of light (bioluminescent, incandescent, phosphorescent…etc)
  4. Basic knowledge of electromagnetic spectrum (radio waves, microwaves…..X-rays, gamma rays)


OPTICS TEST #2 OUTLINE:
Test date: to be determined, after all presentations are completed. This will occur, most likely, on Wednesday, March 9.
  1. One major (20 mark question) Select any optical device or system and explain how it works, using written descriptions, ray diagrams and diagrams as needed. You may also discuss any important details about the optical device / system: where it is used, historical development.....
  2. Very basic questions on the opticss presentations: 1 or 2 marks per presentation.

Chemistry Test #3: Acids and Bases
  1. nomenclature of acids:     binary acids such as HCl or hydrochloric acid and oxy acids such as H2SO4 or sulfuric acid
  2. nomenclature of bases:     Easy! These are just any metal with a hydroxyl group OH-1 on the end, such as sodium hydroxide (NaOH)
  3. How acids and bases are made
  4. Neutralization reactions:     What are they? What are the two products which are always involved?
  5. Acid - base indicators
  6. pH scale
    -key values on the scale such as pH 0, 7, 14
    -pH values of various common liquids (lemon juice, Draino, distilled water) and bodily fluids
    -Calculations such as "by what factor does the acidity change when the pH drops from (for example) 7 to 5."
    -acid rain (What is it?   What are the three main acid-rain producing gases?   What are the key reactions?   What are the effects?)
    ------------------------------------------------------------
    The final test problem does NOT involve acids and bases; it is a continuation of stoichiometry.
  7. One stoichiometry problem, in which you are given the balanced chemical equation and the masses the two reactants. You first have to calculate which reactant is limiting, then proceed from there to calculate the mass of one of the products.
