Transcript of "Light and the Electromagnetic Spectrum"

  1. 1. Light and the Electromagnetic Spectrum<br />
  2. 2. Light as a Wave<br />light is a visible form of energy<br />most of the energy that surrounds us is invisible<br />this energy travels in waves made of electric and magnetic fields<br />called “Electromagnetic Radiation”<br />
  3. 3. Light as a Wave<br />Electromagnetic Spectrum = the entire range of visible and invisible energy waves<br />
  4. 4. Properties of Waves<br />wavelength<br />amplitude<br />amplitude<br />wavelength<br />
  5. 5. Wavelengths of the Electro-Magnetic Spectrum<br />
  6. 6. Wavelength and Colour<br />
  7. 7. Seeing Colour<br />
  8. 8. Pinhole Camera<br />
  9. 9. How Light is Transmitted<br />
  10. 10. Transparent:<br />allows light to pass through<br />Translucent:<br />allows some light to pass through<br />Opaque:<br />allows no light to pass through<br />
