Unpolarized light passes through three polarizing filters. The first one is oriented with a horizontal transmission axis, the second filter has its transmission axis 25.7 degrees from the horizontal, and the third one has a vertical transmission axis. What percent of the light gets through this combination of filters?

 

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?

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 in the three following cases. (a) Three filters are in the stack, each with its transmission axis at 45.0° relative to the preceding filter. (b) Four filters are in the stack, each with its transmission axis at 30.0° relative to the preceding filter. (c) Seven filters are in the stack, each with its transmission axis at 15.0° relative to the preceding filter. (d) Comment on comparing the answers to parts (a), (b), and (c).
