Question

Which category of polarizability strongly depends on Temperature and frequency?

(a) Ionic Polarization

(b) Space-charge polarization

(c) Orientational Polarization

(d) Electronic Polarization

I had been asked this question during an interview.

This intriguing question comes from Types of Polarisation topic in section Dielectrics of Engineering Physics II

Answer 1

Correct answer is (c) Orientational Polarization

To explain I would say: Orientational Polarizability exhibits strong dependence on both frequency and temperature while the electronic and ionic components are nearly independent of temperature and frequency.
