- 6. The minimum change in light intensity that is detectable by the human eye is about 1%. Suppose unpolarized light passes first through a polarizer with a vertical axis, then through a polarizer with its axis at 45°. An observer views the light emerging from the second polarizer. By how much must the angle of the second polarizer axis be increased for the observer to barely perceive a change in the light intensity? A one-significant-figure answer is appropriate.8.
