3. Your Ideas Here!

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

13. APPLICATIONS

13.1. geology

13.1.1. uses polarization microscope for identifying minerals
