  1. 1. 13.4 Color and Polarization By: Desmond Mitchell and DaVon Curvin
  2. 2. Objectives: ❖Recognize how additive colors affect the color of light. ❖Recognize how pigments affect the color of reflected light. ❖Explain how linearly polarized light is formed and detected.
  3. 3. Color Color appears when light reflects off an object ❖For example ➢ Green leaves appear green because they show all wavelengths of light except green
  4. 4. Introduction to Color ❖ The color of an object appears different depending on the lighting conditions. ➢ Like under a blacklight. ❖ The color of an object depends on ➢ wavelengths of light shine on the object ➢ which wavelengths are reflected.
  5. 5. Color ❖ A surface that reflects all colors without absorbing any of its colors shows white. ❖ A surface that absorbs all colors, reflecting none shows black. All colors are caused by light and the way light affects the eyes.
  6. 6. Color ❖White light is a combination of red, orange, yellow, green, blue and violet. ❖When light hits an object wavelengths are absorbed,and reflected.
  7. 7. Color and Light ❖ A prism breaks up light into six colors. ❖ The beams of light can’t be broken up, but can be put back together ❖ If you add two colors of pure light together it creates two different colors

  10. 10. Polarization ❖ The process of transforming unpolarized light into polarized light ❖ Light from most sources has electric and magnetic fields that show at all angles
  11. 11. Polarization ❖ Light is polarized when the all of the electromagnetic waves are transmitted at the same angle. Everything is aligned. ❖ The vibrations of the electric and magnetic fields are parallel to each other.
  12. 12. Polarization ¤Light can be polarized in two ways: ¤Transmission: allows only waves of a certain angle to pass through. ¤Like glare off of glass or shiny objects. ¤Reflection: most waves of light bouncing off of a surface are polarized parallel to that surface ¤Like glare off of glass or other shiny objects.
