Suggestions for Refraction Quiz #1
20132014
The next quiz will be on Tuesday, 5. The quiz
will be a short, onepage quiz, covering both sides of a single
sheet of paper (and possibly one side of a second sheet of
paper). Students can expect the following concepts, skills,
and problemtypes to be assessed on this quiz:
 Define interference and distinguish between
constructive and destructive interference; identify the
unique features of a twopoint source interference
pattern (nodal and antinoldal lines) and explain how
these features are produced.
 Two
Point Source Interference  Anatomy
of a TwoPoint Source Interference Pattern
 Express qualitatively how variations in wavelength or
source separation distance (d) effect the number
of nodal and antinodal lines in a twopoint source
interference pattern.
 Animations of TwoPoint Source Interference
Patterns: #1,
#2 
 Relate the path difference to the wavelength and to
be able to explain the relationship; solve problems
involving path difference and wavelength.
Anatomy of
a TwoPoint Source Interference Pattern  The
Path Difference
 Explain how Thomas Young was able to measure the
wavelength of visible light; discuss how the bright and
dark fringes on an interference pattern are formed; use
Young's equation to solve mathematical problems relating
measurable quantities on a twopoint source interference
pattern.

Applications of Two Point Source Interference
 Distinguish between polarized and unpolarized light
and explain the effect of Polaroid filters and
combinations of filters on the vibrational tendencies of
light.
