your
name
on
your
blue
book .

There
are
ten
problems
on
two
pages.

Work
problem
#
1

Except
for
problem
#1,
no
credit
will
be
given
for
 answers

must
have
correct
units.

Good
Luck! [1] 

 Record
the
answer
that
correctly
completes
the
sentence
in
your
blue
book. a)

Soliton
waves
obey
the
principle
of
linear
superposition
(
True
|
False
)
. b)

The
reason
the
sunset
is
red
is
because

(
blue
|
yellow
|
red
|
none
of
the
above
)
light
is
 strongly
scattered
by
dust
particles
in
the
atmosphere. c)

The
equation

(ı y /ı t )

=
-
 v 
(ı y /ı x )

describes
waves
traveling
to
the
 ( right
 | 
left
 | 
 both
of
the
above
 | 
none
of
the
above d)
In
single
slit
diffraction
at
∫
=
4π,
there
will
be
a

(
maximum
|
minimum
|
none
of
the
above
)
 in
the
intensity
of
light.. e)
The
amplitude
of

hitting
the
floor
will

before
it
was
covered

 none
of
the
above
). g)
In
a
single
slit
diffraction
experiment,
if
the
width
of
the
slit
is
decreased,
the
width
of
the
 diffraction
maximum
on
a
distant
screen
will
(
increase
|
decrease
|
remain
the
same
).
