5.
Reflection and transmission of light waves occur because the
frequencies of the light waves
(3 words)
the natural frequencies of vibration of the objects. When struck by light
waves, the electrons begin vibrating but instead of vibrating in resonance
at a
(1 word) amplitude, the electrons vibrate only
for brief periods of time with
(1 word)
amplitude of vibration. Then the energy is
(1 word)
as a light wave.
6. Transmission occurs when the object is
(1 word). Then the vibrations of the electrons
are
(2 words) to neighboring atoms through the bulk
of the material and reemitted on the opposite side of the object.
7. Reflection occurs when the object is
(1 word). Then the vibrations of the electrons
(3 words) from atom to atom through the bulk of
the material. Rather the electrons of atoms on the material's surface
(1 word) for short periods of time and then
(1 word) the energy as a reflected light wave.
8. Any visible light which strikes the object and becomes reflected or
transmitted to our eyes will contribute to the
(2 words) of that object. So the color
(2 words)
in the object itself, but
(3 words)
which strikes the object and ultimately reaches our eye.
9. The only role that the object plays is that it might contain atoms
capable of
(2 words)
one or more frequencies of the visible light which shine upon it. So if an
object absorbs
(1 word)
of the frequencies of visible light
(1 word)
for the frequency associated with green light, then the object will
appear
(1 word)
in the presence of
ROYGBIV. And if an object absorbs all of
the frequencies of visible light except for the frequency associated with
(1 word) light, then the object will appear red
in the presence of
ROYGBIV.
10. Chemicals which are capable of selectively absorbing one or more
frequency of white light are known as
(1 word).
In Example A, the pigment in the sheet of paper is capable of absorbing red,
orange, yellow, blue, indigo and violet. In Example B, the pigment in the
sheet of paper is capable of absorbing orange, yellow, green, blue, indigo
and violet. In each case, whatever color is not absorbed is
(1 word).
Example A: Reflects
and appears
.
Example B: Reflects
and appears
.
11. Transparent
materials are materials which allow one or more of the frequencies of
visible light to be
(1 word)
through them; whatever color(s) is/are not transmitted by such objects, are
typically
(1 word)
by them. The appearance of a transparent object is dependent upon what
color(s) of light is/are
(1 word) upon the
object and what color(s) of light is/are
(1 word)
through the object.
