Up or down, that's oneĭirection - vertically. Where the electric field is only oscillating in one direction. Values, but I'm only going to see electric fields that point up or down. To see electric fields that either point up orĮlectric fields that point down. What would my eye see? Well, my eye's only going ![]() Straight down that line - and then up and down is up and down, and then left and right, that direction I have the magnetic field, would be this way and that way. Middle, this is this line - so imagine we're looking ![]() Your eye, or a detector, over here, what would you see? Well, if I draw an axis over here, and this point here, in the So what does polarization mean? Polarization refers to theįact that, if this light ray was heading straight toward Just know the direction of the electric field when weįocus on the electric field. Messy if I try to draw both the electric and magneticįields at the same time. Would point at a right angle to the electric fields. It's hard, on something two-dimensional, but you can kind of imagine those looking something like this. There's got to be magneticįields there, as well, that are changing. We know there's not just electric fields. Let's talk about polarization of light. One image is made from clockwise polarized light and the other is made from counter-clockwise polarized light. If you look at the projector of a 3D theater, you will see that they are projecting two separate images to the movie screen. This allows for all colors to reach our eyes and creates a much better viewing experience. Instead of using color filter glasses, now we use polarized glasses where one lens is circularly polarized clockwise (only allows clockwise light through) and the other lens is circularly polarized counter-clockwise (only allows counter-clockwise light through). The red/blue filter works but the problem is the colors of the image will be only shades of red/blue which is not visually appealing. In order to accomplish this with a 2D screen, you need to be able to create a different image for each eye and offset them to force you eyes to change focus to make the images line up (the larger the offset, the closer the image will appear). Incidence and also on the direction of polarization.The way to see something in 3D is your eyes need to be able to focus at different depths to see the image (a 2D screen just has one depth). The intensity of the reflected light depends on the angle of.The product $n\sin\theta$ is the same for the incident and.The angle of reflection is equal to the angle of.We haveĪlready discussed the laws of reflection and refraction in Chapters Of light-or electromagnetic waves in general-at surfaces.
