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 onepage
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 problemtypes to be assessed on this quiz:
 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.
 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.
 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.
