Henderson's Regular Physics Quizzes

(1999-2000 School Year)

 

Suggestions for this week's quiz (Unit 14 Quiz):

This week's quiz on Unit 14 material is tentatively scheduled for Friday, May 5. The quiz will be a one-page quiz, covering one side (likely) of a single sheet of paper. The equation for Snell's law of refraction will be given. Students will need a protractor and ruler. Other than a calculator, no other helps will be provided nor allowed. Students can expect the following concepts, skills, and problem-types to be assessed on this quiz:

  1. Define refraction and describe the cause of refraction; identify and describe the one condition in which light will move from one medium to another and not refract at the boundary.
  2. Use information about the two media on each side of the boundary (e.g., information about the optical density of, the index of refraction of or the speed of light in the two medium) to predict whether a light ray will bend towards or away from the normal at the boundary of the two medium; to construct a refracted ray to express this understanding.
  3. Use Snell's law to determine the angle of refraction at a boundary between two medium (if given the indices of refraction and the angle of incidence); similarly use Snell's law to solve for the fourth parameter if given values of the other three parameters in the equation; interpret the results of such calculations to draw the refracted ray at the appropriate angle.
