The production of light with a specific pattern of oscillation.

• reflection

• polarization

• refraction

• diffraction

A polarizer is used to:

• reduce intensity of light

• produce polarized light

• increase intensity of light

• produce unpolarized light

• transverse

• of high frequency

• longitudinal

• reflected
