Unformatted text preview: ght malice was to be avoided?” Electricity & Magne/sm Lecture 24, Slide 7 CheckPoint 2 Two Polarizers 60 45 30 15 0 1 The second polarizer is orthogonal to the first No light will come through. cos(90o) = 0 Electricity & Magne/sm Lecture 24, Slide 8 CheckPoint 4 Two Polarizers 80 60 40 20 0 1 Any non ­horizontal polarizer aZer the first polarizer will produce polarized light at that angle Part of that light will make it through the horizontal polarizer Electricity & Magne/sm Lecture 24, Slide 9 There is no reason that φ has to be the same for Ex and Ey: Making φx different from φy causes circular or ellip/cal polariza/on: Example: At t = 0 RCP Electricity & Magne/sm Lecture 24, Slide 10 Q: How do we change the rela/ve phase between Ex and Ey? A: Birefringence By picking the right thickness we can change the rela/ve phase by exactly 90o. R...
