For each of the three sheets of polarizing material shown inthedrawing, the orientation of the transmission axis islabeledrelative to the vertical. The incident beam of light isunpolarizedand has an intensity of 1480.0 W/m2. What isthe intensity ofthe beam transmitted through the three sheetswhenθ1 =19.0°, θ2 = 70.0° andθ3 =100.0°?

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.

 This problem deals with light passing through a succession of polarizers as indicated in the sketch:

Unpolarized light, with an intensity of 1000 W/m2 is incident on the first polarizer. The light now passes through a second polarizer, which has its transmission axis rotated by 30 degrees relative to the axis of the first polarizer. What is the intensity of the light transmitted by the second polarizer?

The light transmitted by the second polarizer now encounters a third polarizer, which has its transmission axis oriented at 90 degrees relative to the first polarizer. What is the intensity of the light transmitted by the third polarizer?
