2. Outline
• Introduction to Light
• Activity 1: Lights and their Spectra
• Activity 2: Observing Diffraction
Part 1 : diffraction in water waves
• Activity 3: Observing Interference
- Part 1 : two part simulation
- Part 2 : making interference
• Activity 4: Observing Iridescence
- Part 1 : peacock feather
- Part 2 : bubble soup
• Product Idea: perforated cement

3. Introduction:
Light is electromagnetic radiation that has
a visible light wavelength in the range
from a 400-750 nm.
- Nano : is measuring unit = 10-9

4. Activity 1: Lights and their
Spectra:
Objective : observe the light spectra
Procedure : using glue , attach the circular
grating to be one end of the tube using a tape
and other side we use CD after labeling it .

5. Results :
conclusion : each element unique spectrum
Both discrete and
Continuous spectrum Continuous spectrum

6. Activity 2: Observing
Diffraction:
We wants to observe diffraction in water wave
Procedure :
Wide an opining High an opining An obstacles

7. Activity 3: Observing
Interference:
 Interference is a phenomenon
which two waves superpose to from a
resultant wave of greater or lower amplitude.

8. Activity 3: Observing
Interference:
The red line : construvtive
interference
The green line : destructive
interference
Destructive is
Interference : between a top
wave and a bottom wave and
it result in showing a black
color .
Construvtive is
Interference : between a top
wave a top wave result in
showing a white color .

9. Activity 4: Observing
Iridescence:
The color in peacock feather is not from pigment
its due to interference and nano-scale structure .

10. Activity 4: Observing
Iridescence:
Soup bubble :
Conclusion : color in soup bubble
due to the film interference .

11. Product Idea
Title: perforated cement
A building in one of its sides will be carved in an artistic form:
In the course of the day there is sunlight and at the same time
we are lighters and this is a waste of energy
How can we solve this problem?
1- that we forget one of the raft art from
In this way we have exploited the light in a way that is useful so
that in the day the source of the introduction of light and at
night we open the source of energy and will bring out the light
Of the holes.

12. Title of your product idea
Hypothesis:
)‫الفرضية‬(
Suppose that the cement will solve the problems of
many people living in the desert and will help them
to obtain light easy and easy to simplify the
placement of cement in front of the sun or the
mechanism of light and light out from everywhere.

13. Title of your product idea
Your product story:
(‫مشروعك‬ ‫أو‬ ‫اختراعك‬ ‫قصة‬)
On the day of our invention of this project we saw
the stories of people who suffer from the lack of
light in the day and this may cause them a
decrease in vitamins and decided to resolve this
problem group AL-BAIRAQ and workshops that
we have also helped us to have this idea and solve
these problems experienced by people.

14. Title of your product idea
Results)‫النتائج‬(
What are the uses and benefits of your product ?
Did you solve the problem that you invented to
solve it ?
1 - used to illuminate the house in a healthy way, and the
benefits of this product that we exploited the light of the
sun correctly.
 Images and drawings for your project should
include this part :

15. Title of your product idea
Recommendations:
)‫التوصيات‬(
Do you recommend more research and testing on your
invention or product?
When the building is finished and is finished and ready for use, we
assume that one will build another building next to the sunken building
so will isolate the sunlight and this problem we will use fiber optics from
the place where the sunlight to the building.
If you have encountered problems or obstacles in your
experiments or test your invention, what are your
recommendations to overcome ?
We had difficulty taking measurements of turmeric, we also faced the
force of cement that would come down on the glass.

16. Conclusions
(Overall)
Our experience was so helpful and exited and we
learn about light in new way that helped us to
invents this product .
This workshop helped us to let us think and to be
creative .

17. Acknowledgment
Thank all people, teachers, friends, and your school that
supported you during your journey in AL-BAIRAQ project.
Also don’t forget to thank AL-BAIRAQ team and the
sponsors who gave you the opportunity to participate in
AL-BAIRAQ project, create and innovate.
