PART A: If a vertically oriented, ideal polarizing sheet transmits 50% of the incident unpolarized light and the polarizing sheet is now rotated through 45 degrees, what fraction of the incident intensity now passes? My guess is that 0% of the incident intenisty would pass through, but I am not sure if I am wrong and 100% or 50% of the incident intensity passes through instead. Any answer or explaination would be greatly appreciated. PART B: Now, if an ideal polarizing sheet transmits 90% of the incident partially polarized light, what percentage of the incident light is polarized?
I am having difficulty understanding polarization of sheets and the incident intensity of light that passes through it. My question has three parts:
PART A: If a vertically oriented, ideal polarizing sheet transmits 50% of the incident unpolarized light and the polarizing sheet is now rotated through 45 degrees, what fraction of the incident intensity now passes?
My guess is that 0% of the incident intenisty would pass through, but I am not sure if I am wrong and 100% or 50% of the incident intensity passes through instead. Any answer or explaination would be greatly appreciated.
PART B: Now, if an ideal polarizing sheet transmits 90% of the incident partially polarized light, what percentage of the incident light is polarized?
Here, I am assuming 100% of the light is polarized, but I am not entirely sure. Any answer or explaination would be greatly appreciated.
PART C: Similar to PART B, an ideal polarizing sheet transmits 90% of the incident partially polarized light. But what percentage of the transmitted light is polarized?
I am not entirely sure what the difference between transmitted light and incident light is, so I am not sure of the answer. Any answer or explaination would be greatly appreciated.
Thank you for your time, any answers or clarification that you can provide would be greatly appreciated :)
