Suggestions for Refraction Quiz #1
20142014
The first Refraction quiz will be on Tuesday, September
24. The
quiz will be a twopage quiz, covering three sides of a sheet of paper.
Bring your centimeter ruler/protractor and be
ready to think, diagram, and calculate. 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; define
the angle of incidence and the angle of refraction. (MOP,
sublevels 1
and 2)

 Identify and use the relationship between light speed
and the index of refraction. (MOP,
sublevel 3)
 Optical
Density and Light Speed 
 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.(MOP,
sublevel 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 by drawing the
refracted ray at the appropriate angle; to combine an understanding of
the physics of refraction with an understanding of trigonometric and
geometric relationships.(MOP,
sublevel 4 and WebAssigns)

Tracing
and ProblemSolving
 Use Snell's Law and the path of light through a
material to
determine the index of refraction of an unknown material. (MOP,
sublevel 4)
 Determination
of n Values 
 Combine an understanding of Snell's Law with an
understanding of right triangle relationships (SOH CAH TOA) to analyze
and solve a difficult refraction plus
problem.
 Understand and use processes similar to those used in labs

e.g., graphical analysis of data, numerical analysis, laser path
analysis, etc.
