A Linearly Polarized Electromagnetic Wave Is Sent Through Two Sheets

question 66

Multiple Choice

A linearly polarized electromagnetic wave is sent through two sheets of polarizing material. The first sheet, A, is oriented so that its transmission axis makes an angle of 30° with respect to the incident electric field of the wave. The second sheet, B, is oriented so that its transmission axis makes an angle of 90° with the incident electric field of the wave. The incident beam has an electric field of peak magnitude E₀ and average intensity S₀.
-What is the average intensity of the wave after it passes through A?

• A)0.30S₀
• B)0.50S₀
• C)0.60S₀
• D)0.75S₀
• E)0.87S₀
