| Abstract: | Using red and green laser beam to produce two polarized light beams whose polarization directions are respectively parallel and vertical to the incidence plane,then the two polarized light beams are mixed.By changing the polarization configuration of the beam and the incident angles,then the color and the brightness of the reflected and transmitted light spot will vary accordingly,Malus law,Fresnel law and Brewster law could be demonstrated. |

| Keywords: | double color laser polarization Fresnel formula Brewster law Malus law |
