Unformatted text preview: ight hand rule This changes linear to circular polariza/on and is called a quarter wave plate Electricity & Magne/sm Lecture 24, Slide 11 “talk something about intensity” NOTE: No Intensity is lost passing through the QWP ! BEFORE QWP: AFTER THE SAME! Electricity & Magne/sm Lecture 24, Slide 12 Right or Left? “red fox” got it? Right circularly polarized Do right hand rule Fingers along slow direc/on Cross into fast direc/on If thumb points in direc/on of propaga/on: RCP Electricity & Magne/sm Lecture 24, Slide 13 Circular Light on Linear Polarizer Q: What happens when circularly polarized light is put through a polarizer along the y (or x) axis ? A) I = 0 B) I = ½ I0 C) I = I0 X Half of before 1/2 Electricity & Magne/sm Lecture 24, Slide 14 CheckPoint 6 Case A Case B 50 38 Case A: Ex is absorbed Case B: 25 (Ex ,Ey) phase changed 13 0 1 Electricity & Magne/sm Lecture 24, Slide 15 Intensity: ￿ ￿ 2 I = ￿0 c ￿E 2 ￿ + ￿Ey ￿ x E AS PH QW Plate CH AN GE Both Ex and Ey are s/ll there, so intensity is the same Electricity & Magne/sm Lecture 24, Slide 16 ￿ ￿ 2 I = ￿0 c ￿E 2 ￿ + ￿Ey ￿ x B OR S AB Polarizer CO M PO NE NT Ex i...
