noun plural -ties

the state or quality of being two or in two parts; dichotomy

The propagation of electromagnetic radiation is analysed using wave theory but its interaction with matter is described in terms of photons. The condition of particles such as electrons, neutrons, and atoms is described in terms of de Broglie waves

geometry the interchangeability of the roles of the point and the plane in statements and theorems in projective geometry
