An unpolarized beam of light is incident on a stack of ideal polarizing filters. The axis of the first filter is perpendicular to the axis of the last filter in the stack. Find the fraction by which the transmitted beam's intensity is reduced if the three filters are in the stack, each with its transmission axis at 45 degrees relative to preceding filter.

Three ideal polarizing filters are stacked, with the polarizingaxis of the second and third filters at 29.0and 58.0, respectively,to that of the first. If unpolarized light is incident on thestack, the light has intensity 110 after it passes through thestack.

If the incident intensity is kept constant, what is the intensityof the light after it has passed through the stack if the secondpolarizer is removed?

Unpolarized light falls on a stack of three polarizing sheets.The transmission axes of the top and bottom sheets are 90 degreeswith respect to each other. The middle sheet has its transmissionaxis aligned at 45 degrees with respect to the top and bottomsheets. What fraction of incident unpolarized intensity istransmitted through the stack?

The light in Problem 62 travels toward a workbench and encounters two polarizing filters.

a. If the light passes first through a filter with its transmission axis at an angle of from the z direction, and then through a filter with its transmission axis at an angle of from the z direction, what is the final intensity of the transmitted light?

b. If, instead, the light passes first through a filter with its transmission axis at an angle of from the z direction, and then through a filter with its transmission axis at an angle of from the z direction, what is the final intensity of the transmitted light?

 

Problem 62:

Suppose you have a polarized light source in your lab that has an intensity of , where the electric field oscillates in the z direction. The light travels toward a workbench where you can send it through either one of two polarizing filters.

a. If the light passes through a filter with its transmission axis at an angle of from the z direction, what is the intensity of the transmitted light?

b. If, instead, the light passes through a filter with its transmission axis at an angle of 90.0° from the z direction, what is the intensity of the transmitted light?
