3. These are the seven
colors of the rainbow.

4. This is light energy that
can be seen and broken
into all the colors of the
rainbow.

5. This is our most
important source of
light.

6. These are several sources
of light.

7. This tool can be used
to separate white light
into all the colors of
the rainbow.

8. Light moves in this
direction.

9. Unlike sound waves, light
waves can move through
this.

10. This is the distance from
one point on a wave to
the same point on the
next wave.

11. These are the high and
low points on a wave.

12. Daily Double!!!
A thin beam of light
that is more powerful
than regular light.
These waves all have
the same wavelength.

13. This object appears to be
a source of light in our
solar system, but it really
only reflects the light
from the sun.

14. Kinds of energy that
move in waves, but
cannot be seen are these.

15. Objects made of this type of
material allow light to pass
through them, so we can see
what is behind them.

16. When light moves from one
material to another, it changes
speed and bends. This is known
as______________.

17. This person discovered
that white light is made
up of all the colors of the
rainbow.

18. This type of material
does not allow light to
pass through it.

19. This type of material
scatters light so that
objects behind it seem
blurry.

20. You cannot see a
reflection in rough
surfaces because when
light rays hit them this
occurs.

21. This word means “to
allow to pass through”.

22. This type of lens is thinner in the
middle and makes objects look
smaller.

23. These appear when
sunlight passes
through water droplets
in the air.

24. This is the acronym we
use to remember the
colors of the visible
spectrum.

25. This color has the
shortest wavelength.

26. A red shirt looks red
because it does this.

27. Objects that appear to be
this color absorb almost
all of the light that hits
them.

28. In order to see, we need this.

29. We cannot see around
corners because of this.

30. Light rays hit these
surfaces at a certain
angle and then reflect off
them at the same angle,
providing a clear image.

31. When light hits an opaque
object, we can make
these.

32. When light bounces back
from an object, it is
known as this.
