The
predominant
color
of
the
reflected
light
will
be
that
wavelength
for
which
the
 interference
of
the
reflected
light
is
a
maximum.

Light
reflected
off
the
first
air-oil
surface
will
 be
inverted
by
the
optically
denser
oil,
and
light
reflected
off
the
second
oil-water
surface
will
be
 inverted
by
the
denser
water.

Thus,
the
only
difference
between
the
waves
is
caused
by
the
path
 difference
of
2 t 
where
 t 
is
the
thickness
of
the
oil.
