Physics Quizzes
(199899 School Year)
Suggestions for this week's quiz
(Unit 13 and Unit 14 Quiz):
This week's quiz on Unit 13 material is tentatively
scheduled for Friday, April 30. The quiz will be a onepage
quiz, covering both sides of a single sheet of paper. The
equations for the magnification ratio, the mirror equation,
and 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. Roughly
onehalf of the quiz will pertain to curved mirror
reflection and onehalf will pertain to refraction of light.
Students can expect the following concepts, skills, and
problemtypes to be assessed on this quiz:
 An ability to construct ray diagrams for concave
and convex
mirrors in order to determine the location, orientation
and type of image if given the object location.
 An ability to recognize the relationship between the
object
location and the image characteristics for a concave
mirror. While ray diagrams would be useful tools in
determining those relationships, it is expected that you
will have internalized the relationships by quiztime.
The short lab and ray diagram worksheet and Friday's
class period will be a valuable aid. Consider the
following ray diagram links:
 Use the mirror eqution and the
magnification ratio for concave
and convex
mirrors in order to solve
mathematical problems in which the image location and
size are determined; to relate the results of one's
calculations to the predictions which would be made by
the use of a ray diagram.
 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.
 An understanding of previous concepts from the light
units. Use the links below to see the Studying
