Polarization Polarization of light is a phenomenon due to which the vibrations of light are restricted in a particular plane. To detect plane polarized light Makin g distinction between the unpolarized and plane polarized light cannot be done using the naked eye or the polarizer. So a crystal called analyzer is used to analyze the nature of light. The intensity of light remains unaffected when the axes of the polarizer and the analyzer are parallel to each other and it becomes minimum when
