complementarity - definition - quantum mechanics
Definition: In quantum mechanics, the wave and particle models are complementary. There is correspondence between particles of momentum p and energy E and the associated wavetrain of frequency ν=E/h and wavelength λ=h/p, where h is Planck's constant. A measurement showing the wave character of an object cannot prove the particle character in the same measurement and vice versa.
