2. Outline
• Introduction
• Summary of Activities
• Product Idea

3. Introduction
Light is the natural agent that stimulates sight
and makes things visible

4. Summary of activities
Activity 1: light and their spectra
We built spectroscope to
analyze spectrum of different
light source.
Activity 2: Observing diffraction
We observed diffraction of
waves through variety of
mediums such as water waves.

5. Summary of activities
Activity 3:Observing Interference Activity 4 Observing Iridescence
There are two main types of
structures that create the colors
observed in Iridescence:
1- Thin Film interference
2- Surface structure
Interference is the effect of two
or more waves moving through
the same place at the same time.

6. GLOWING BRACELET
Final Project

7. Light therapy is used to treat sleep disorders,
depression and seasonal mental disorders.
Scientists have discovered that bright light result in
increasing blood pressure.
Also Ultraviolet light exposure release nitric oxide
from the skin into the blood stream lead to decrease
in blood pressure.
Glowing Bracelet
Introduction

8. Glowing Bracelet
Aim of the work (objectives) (‫البحث‬ ‫)هدف‬
Build bracelet to help in reducing blood pressure
using ultraviolet and increasing the blood
pressure using bright light.

9. Glowing Bracelet
Hypothesis: (‫)الفرضية‬
Glowing Bracelet will help reducing the blood pressure for hypertension
patients and increasing blood pressure for hypotension patients.

10. Glowing Bracelet
Methods and Materials
Used acrylic sheet to design bracelet, then use
both ultraviolet and a light with bright
intensity, to attached it to the bracelet.

11. Glowing Bracelet
Results: (‫)النتائج‬
The exposure to the light helped increasing the
blood pressure using bright light and decreasing
the blood pressure using ultraviolet.

12. Glowing Bracelet
Recommendations: (‫)التوصيات‬
We recommend that our project
should be used in hospitals, clinics
and should be available for all the
patients, also we recommend more
research should be done to
develop this idea.

13. Glowing Bracelet
Conclusions
We have discovered that light can be
used to solve many problems including
medical purposes, and not only for
decoration purposes.
