Homework Statement
Unpolarized light passes through a polarizer oriented at 33 degrees from the horizontal axis.
1) At what angle (relative to the horizontal axis) would you place a polarizer so that no light passes through it?
2) At what angle (relative to the horizontal axis) would you...
Homework Statement
Describe how to rotate the plane of polarization of a plane-polarized beam of light by $90^\circ$ and produce only a 10 percent loss in intensity using "perfect" polarizers.
The solution says to use 24 polarizers, with each at an angle of $3.75^\circ$ with the next...
Hello,
I keep myself busy by trying to model/predict standing waves in the optical path of a heterodyne spectrometer we built in our lab.
We split and combine the local oscillator and the sky (it's for astronomy) with a beam splitter. Our beam splitters are wire grid polarizers.
The...
Does a polarize simply filter photons
or
does it change the polarization of photons (as well)?
let's consider only one photon being sent, at a time, via the polarizerI think the answer might be that:
for photons polarized at say 45 degree to the horizontal (or vertical) plane of the polarizer...
Homework Statement
Initially unpolarized light with an intensity of 240W/m2 is incident on a series of two polarizers. What should be the angle between to the axes of the two polarizers such that the transmitted intensity after the second polarizer is 37.5% of the incident one?

Hi:smile:
I have a question about a circularly polarized wave.
Once this wave passes through a linear polarizer - how is the wave intensity changed?
Someone has told me that the intensity decreases to its half value, but I’ve read somewhere the intensity is not changed…
So… what is the...
1. A 200 mW horizontally polarized laser beam passes through a polarizing filter whose axis is 25 degrees from vertical.
2. Malus's Law
3. Ok, so I will use theta = 65 degrees in the I = I0cos(theta) equation, right? But how do I calculate I0 knowing only power and not area?
Homework Statement
Three polarizing filters are stacked, with the polarizing axis of the second and third filters at angles of 17.4^\circ and 59.8^\circ, respectively, to that of the first. If unpolarized light is incident on the stack, the light has an intensity of 74.0 W/cm^2 after it passes...

I apologize for my bad sketch.
Hi,
I need help understanding how this setup changes the polarization of the outgoing beam if the entire setup is rotated.
There are 3 mirrors (gold): 2 mirrors are adjacent and set at 30...
Anyone know why circularly polarized light, when observed after passing through a linear polarizer, would exhibit minima in intensity? It would seem to me that, since the linear polarizer only allows a particular plane of vibration through, and the circularly polarized light rotates about with a...
When a beam of light is passed through a polarizer, it is polarized in a certain direction, say the x-direction. So, the irradiance or the energy of the initial beam is now reduced. The y-direction electric field could not pass through.
So, where has the y-direction electric field gone, which...
