4. polarization
4.1. it is the process of transforming unpolarized light into polarized light
4.2. he process of transforming unpolarized light into polarized light
5. light waves
5.1. it is an electromagnetic wave that is TRANSVERSE in nature.
5.2. are created by electric charges that vibrate in a VARIETY OF DIRECTIONS, thus creating an electromagnetic wave that vibrates in a variety of directions
5.3. most light sources like bulbs, lamps, and candles are UNPOLARIZED
6. polarized light
6.1. Polarized light waves are light waves in which the vibrations occur in a single plane
6.1.1. LINEAR POLARIZATION
6.1.1.1. the electric field of light is confined to a single plane along the direction of propagation.
6.1.2. ELLIPTICAL POLARIZED
6.1.2.1. the electric field of light describes an ellipse.
6.1.3. CIRCULAR POLARIZED
6.1.3.1. the electric field of light consists of two linear components that are perpendicular to each other, equal in amplitude, but have a phase difference of π/2
7. unpolarized light
7.1. A light wave that is vibrating in more than one plane.
8. PLANE OF VIBRATION
8.1. the plane that contains the polarized light
9. PLANE OF POLARIZATION
9.1. the plane perpendicular to the plane of vibration
10. POLARISCOPE
10.1. POLARIZER
10.1.1. instrument where light gets polarized
10.1.1.1. ex: polaroid filters
10.2. ANALYZER
10.2.1. an instrument that detects whether a light ray is polarized or not
11. BREWSTER'S LAW
11.1. states that when a light incident at a polarizing angle θp at the interference of a transparent medium, the refractive index of the medium with respect to the surrounding medium is equal the tangent of the polarizing angle
12. MALUS' LAW
12.1. states that when a completely plane polarized light is incident on an lyzer
