3. Introduction
Background about light
Light is an electromagnetic radiation within a certain
portion of electromagnetic
spectrum.
Light is referred to as visible
light which is visible to the human eye.
When a light diffracts, it produces
a spectrum of colors with different
wavelengths .

4. Activity 1: light and their spectrum
• Observe the spectrum of different sources of light.
Making of a spectroscope using simple
utilities
Result of spectrospectrem
Discrete spectrum
(fluorescent light) and
continuous spectrum
(incandescent light)

5. Activity 2: observing diffraction
part A: diffraction in water wave
• Objective: To see how the water waves diffract
when passing through a slit.

6. Activity 2: observing diffraction
part A: diffraction in water wave
• Results: diffraction was more visible when the
slit width was small. Big slits showed nearly no
diffraction at all.

7. Activity 2: observing diffraction
part B: diffraction simulation
• Objective: to observe the diffraction of the
waves using a computer simulation.
The most visible diffraction is
when the sit width was one half
the light wavelength

8. Activity 2: observing diffraction
part C: diffraction of light through opening
• Objective: to observe the diffraction of the
waves using different sizes of slits

9. Activity 3: observing interference
part A: Making interference transparent
• Objective: observe constructive and destructive
interference and nodes and antinods.

10. Activity 3: observing interference
part B: two slits experiment
Activity 3: observing interference
part B: two slits experiment
• Objective : to observe the wave interference
as the bass through two slits
The wave interfered as they
passed through two slits. This
resulted in areas of darkness
and areas of bright light.

11. Activity 4: observing iridescence
Nail polish Peacock FeatherThin film
Objective: to observe iridescence in different objects like a peacock
feather, thin film and a nail polish

12. Activity 4: observing iridescence
Nail polish
Thin film
Peacock Feather
Iridescence can be due to thin film interference or the structural
features of the object itself.

13. Fountain Hologram
Our idea is to build fountain using hologram
instead of water. So it will dcrease the uneeded
uses of water

14. Materials and Method
 -Large pieces of glass
 -Super glue
 -Cutter
 -Playdough
 -Paper
 -Long ruler
 -Protractor
 -Big screen ( iPad pro )

15. Materials and Method
1-We cut 4 pieces of glass into 4 trapezium using the
dimensions above.
2-We take a large paper and write the area of ​​the pyramid
base.
3-Place two small cards made of putty on each side of the
paper.
4-Pull the paper carefully so that the balls do not burn.
5-Then we fix the first hand by placing it on the cards and
make sure that the edge is on the corner 45.
6-After we have established the first piece, we take the
second and put the playdough on one side and formulate it
in the established and so we do for the rest of the parties to
equip the pyramid.
7-In the end we take a big screen with the video of the
hologram (water) that we will be showing.
8-We made a wooden base to accommodate the project so

16. Results and Recommendations
- Three-dimensional portrait of water
fountain.
- Fountain Hologram will prevent the
wastage and usage of water.
- This project would be used in public places
such as amusement parks and hotels
where it will increase children’s safety

17. The benefit from our experience that we
were able to learn new things by
researching and inventing our project.
Albairq made us more interested about
light .it made us learn new information and
facts .
Albairaq made us more intrested to use
social media for education .which made the
project fun to participate in
Conclusions

18. We would like to thank Qatar university and the centre for
advanced materials for allowing us to participate in Al-Bairaq
project .
All thanks to our sponsors, the centre for
advanced material, the Unesco ,
Qatar ministry of education and higher
education, and shell .
Many thanks for our school ,al arqam
academy ,for helping us to participate in
this project
