Complementarity principle (N. Bohr)
The principle which a given system cannot exhibit wave-like and particle-like both behaviors at the similar time. i.e., certain experiments will demonstrate the wave-like nature of a system, & certain experiments will demonstrates the particle-like nature of a system, however no experiment will reveal both simultaneously.
An α particle is a positively charged particle. Rutherford observed the behaviour of these particles when they approach the interior of the atoms as shown in fig. Rutherford ob
