The video tutorial explains the concept of diffraction, where light bends when passing through a slit, creating a pattern of brightness and darkness. It introduces De Broglie's hypothesis that all matter particles, like electrons, exhibit both particle and wave nature. The tutorial derives De Broglie's equation, comparing photon energy equations and applying the concept to material particles, showing that the wavelength associated with a particle is inversely proportional to its momentum.
