1 [with object] Physics restrict the vibrations of (a transverse wave, especially light) wholly or partially to one direction:some of the light is polarized so that it vibrates in only one plane (as adjective polarized)polarized laser light (as adjective polarizing)a polarizing microscope
2 [with object] Physics cause (something) to acquire polarity:the electrode is polarized in aqueous solution
3divide or cause to divide into two sharply contrasting groups or sets of opinions or beliefs: [no object]:the cultural sphere has polarized into two competing ideological positions
