1. Light and the Electromagnetic Spectrum

2. Light as a Wave light is a visible form of energy most of the energy that surrounds us is invisible this energy travels in waves made of electric and magnetic fields called “Electromagnetic Radiation”

3. Light as a Wave Electromagnetic Spectrum = the entire range of visible and invisible energy waves

4. Properties of Waves wavelength amplitude amplitude wavelength

5. Wavelengths of the Electro-Magnetic Spectrum

6. Wavelength and Colour

7. Seeing Colour

8. Pinhole Camera

9. How Light is Transmitted

10. Transparent: allows light to pass through Translucent: allows some light to pass through Opaque: allows no light to pass through

12. Rough Surface
