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.

A horizontal 5.0 mW laser beam that is vertically polarized is incident on a polarizing sheet that is oriented with its transmission axis vertical. Behind the first sheet is a second sheet that is oriented so that its transmission axis makes an angle of 30° with respect to vertical. What is the power of the beam transmitted through the second sheet? What would the power of the beam transmitted through the second sheet be if the lazer beam was Unpolarized?

A beam of unpolarized light of intensity 4.04E3 W/m2 passes through a series of ideal polarizing filters with their polarizing directions turned to various angles as shown in the figure. If the middle polarizer is removed, what is the light intensity at point C (in W/m2)?
In Figure (a) below, unpolarized light is sent into a system of three polarizing sheets. The angles 8₁, 82, and 83 of the polarizing directions are measured counterclockwise from the positive direction of the y axis (they are not drawn to scale).

A beam of unpolarized light shines on a stack of five ideal polarizers, set up so that the angles between the polarization axes of pairs of adjacent polarizers are all equal. The intensity of the transmitted beam is reduced from the intensity of the initial beam by a factor of a = = 0.215. Ө Find the angle between the axes of each pair of adjacent 0 = rizers.
