1. Put your 3D glasses on now… The red goes on your left eye.

17. Red Cyan 3D Glasses Overlapping two slightly different images of opposite colors can produce a 3D image. Your brain will combine the images, creating a 3D effect. – The red filter only allows red light through – The cyan filter allows blue and green light through Rotating Brain!

19. Color Vision

20. Color Vision Deficiency / (Color Blindness) About 0.4% of women and 8% of men are affected by some type of color blindness The most common type of color blindness is a form of red- green color blindness called deuteranomaly. This means that the green cones of the eye are sensitive to “incorrect” wavelengths, affecting perception of the colors green and red. People can also have absent or non functioning green cones, causing a more severe form of red-green color blindness. Less commonly, people can be blue-yellow color blind. Very rarely, people can have monochromacy, and only see in black, white, and gray.

30. Polarization Light travels as a transverse wave, with the electric and magnetic fields oscillating perpendicular to the forward motion of the wave Light from the sun, from a lamp, or from a candle is all unpolarized – Unpolarized light oscillates in many planes – Polarized light only oscillates in one plane

31. Polarization Polarization occurs when you take unpoloraized light and make it polarized Using a polarizing filter (or Polaroid) absorbs some of the incoming light, reducing the amount or intensity of light passing through the filter
