1. SPS9
Students will investigate the properties
of waves.

3. All electromagnetic waves travel at 300,000
Km/s in the vacuum of space. This is the
Speed of light.
Air --- slightly less than 300,000km/s
Water ,000 km/s
Glass ,000 km/s
Diamond – 124,000 km/s

4. Photons depend on the frequency of the wave
not the amplitude (energy).

6. Objects can absorb light, reflect light, and
transmit light depending on the type
of matter they are made of.

7. Opaque only absorbs light and reflects it.
The blue cup is an example of an opaque material.

8. Aluminum foil is an example of an opaque
material because it reflects light

9. Translucent materials allow some light to pass
through them. Which cup is translucent?

10. Transparent materials transmit almost all the light.
The clear plastic cup is transparent.

12. The Law of Reflection says that the angle of
Incidence always equals the angle of reflection.

13. Diffuse reflection

14. Every material has an index of refraction, the larger the index, the greater the amount by which the speed of light is reduced.

15. How do we see color?

16. How do 3 D glasses work? HD glasses?
Block blue light
for extreme clarity
research says they
are hype.

17. Light as waves, photons, and rays!!

19. Copy:
Virtual Image – your brain perceives an image
even though no light rays pass through it.
Your brain always perceives light rays as
though they have traveled in a straight line.

20. Copy:
Real Image is formed when light rays converge
to form the image.

21. Virtual Images: Your brain thinks that the light
Rays that reflect off of the mirror come from
a point behind the mirror.

22. Draw: Concave Mirror Real image C = optical axis F = focal point
Magnified inside the focal pt.

23. Draw:
Convex mirrors diverge
light rays. Objects look closer
than they truly are.
Virtual Image

24. Convex Lens is thicker in the middle than at the edges.
Depending on the
position of the
lens and the object,
the object
may appear
real or upside
down.

25. Concave lens
The image is always
virtual, upright, and
Smaller.

28. Summary:
Light rays bounce off of mirrors and
pass through lenses.
Virtual and real images depend on the
behavior of these light rays.
Today, you should have been able to
draw a concave and convex mirror
draw a convex and concave lens
explain the difference between a virtual and a real image.

29. Groups: Choice A
Soft Blue Book page 212
Using the materials provided you, prepare
a home interiors presentation on the following:
The types of windows available for an upstairs
bathroom.
Based on the science of light, and the
customers’ needs, explain which window works
best under certain conditions.

30. Choice B
You are making a presentation and teaching a class for Bass Pro Shop on the art of spear fishing.
Be sure to discuss the behavior of light in different mediums and the index of
refraction using the materials provided you.

31. Choice C
You are teaching a 4th grade class on mirrors.
Design a hands on activity using the materials
provided for your students to learn about
the laws of regular and diffused reflection.
You might want to use a County Fair theme
and make a fun house with different kinds of mirrors.

32. Choices A – Home interior presentation
B – Teaching a class of Bass Pro Shop on the art of spear fishing
C – Teaching a 4th grade class on mirrors
