1. Awesome Light

2. Light & Shadows In Everyday Life

3. Light as Wave Frequency Color determined by frequency
Energy determined by frequency

4. Light as Particle Photons Energy : hf
Number of photons = Amount of Light

5. Combination Travelling Light  Wave
Hitting Objects  Particle (photons)

6. 1st Experiment Photons Less light = Less photons
What we will need
Black Is not ABSOLUTE Black
Photons
Less light = Less photons
Black objects absorb most of the emitted photons
A black object
A lots of photons

7. 2nd Experiment Less light = Less photons Photons Identity  hf
Shadows have COLOR
What we will need
Less light = Less photons
Photons Identity  hf
Frequency determines the color of light
Colored light source
Object for the shadow
A camera (sensitive)

8. Conclusion Not all black is ABSOLUTE black
Shadows have the same color with the light emitted from the light source (frequency, particle & wave)
