Unpolarized light passes through two polaroid sheets. The axis of the first is vertical, and that of the second is at 26.0° to the vertical. What fraction of the initial light is transmitted?© BrainMass Inc. brainmass.com October 24, 2018, 5:59 pm ad1c9bdddf
^ denotes power
Let the intensity of unpolarized light be I
Then the intensity of light beyond the first polaroid sheet will be I / 2.
If we denote this intensity by I1 then I1= I /2
(This is because in the incident unpolarized light the amplitude of the electric vectors parallel to the the axis of the first polaroid ...
The solution calculates the fraction of light that is transmitted.
The Polarization of Light
Please solve and explain
Two pieces of Polaroid are held against the light.
Can you look through them by themselves?
When they are stacked on top of each other?
What happens if you rotate one of the Polaroids while keeping the other one fixed. Explain why you observe a variation in transmitted light intensity.View Full Posting Details
