👉 In quantum mechanics, a polarized wave is a state in which two orthogonal electric or magnetic fields are present. If one field has a larger magnitude than the other, it will be called a "polarized" field. The polarization of light can also occur in situations where there is an electrical or magnetic field that causes a change in the direction of light's wave vector. This phenomenon is known as polarized light and can be observed through certain devices like spectrometers.
