The document summarizes 4 activities conducted by a student group to investigate properties of light. In Activity 1, they constructed a spectroscope to observe the spectra of different light sources. In Activity 2, they observed diffraction patterns using a slit. Activity 3 explored light interference. For Activity 4, they studied iridescence. The group hypothesized how to create a rainbow effect and developed a product idea for a "bright bottle". They thank those who supported their work in the Al-Bairaq competition.

Outline

3. The light is electromagnetic radiation with
portions of electromagnetic spectrums,
The main light is Sun on earth which is
visible and usually, the visible light has
400-700 nm wavelength.

4. Activity 1: Lights and their Spectra
Objective:
To find each light function and find out
how does it deals with spectrum.
Materials to make spectroscope:
1-Tape
2-tube
3-black paper
4-CD
Steps to make it:
Cut the paper in to circle shape, peel of the skin of
CD and attach it to the tube.

5. Activity 1: Lights and their Spectra
Results:
we found each light sources.

6. Activity 2: Observing Diffraction
Objective:
We wanted to know how would diffraction work in
water form.
With tiny split.
Explanation:
With wide opening

7. Results:
The result we got from our experiment we did the thinner the split gets
waves the rounder waves, and the wider waves gets the wider waves gets.

8. Activity 3: Observing Interference
Objective:
We wanted to know how does light observes the
interference.
Explanation:

9. Results:
we found out how would it work in form of light.

10. Activity 4: Observing Iridescence
Objective:
We wanted to know what kind of iridescence there are.

11. Bright bottle

12. Hypothesis
We inserted the light in way to make rainbow.

13. Product story:
The reason we came up with this idea.

14. Product idea:
