Suggestions for this week's quiz (Unit 13 Quiz #3):

This week's quiz on Unit 13 material is tentatively scheduled for Friday, May 1. The quiz will be a one-page quiz, covering both sides of a single sheet of paper (or a little less). The equations for Snell's law and n=c/v will be given; the equation for the critical angle will not 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.
  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 appropirate angle.
  4. Describe the behavior of light waves at a boundary (reflection, transmission and refraction, etc) and the dependence of this behavior upon the angle of incidence; define total internal reflection and identify and discuss the two conditions under which it occurs.
  5. Describe what the critical angle is and be able to use index of refraction values to calculate the critical angle for two given materials; interpret the results of such calculations to construct a incident ray (and corresponding refracted ray) at the critical angle and other incident rays which undergo total internal reflection.
  6. Define dispersion and describe the conditions under which it is likely to be observed; explain the cause of dispersion using both words and diagrams.
  7. Identify and explain the causes of various refraction and total internal reflection phenomenon, including but not limited to dispersion by prisms, rainbow formation, use of optical fibers, the sprakling of diamonds, the lengthening of days, mirage formation, etc.)
  8. An understanding of previous concepts from this unit. Use the links below to see the Studying Suggestions for the previous quizzes from this unit.
