The Dual Nature of Light and Electrons

This chapter explores the wave-particle duality of light and electrons, beginning with the double-slit experiment that illustrates light's wave-like properties. It discusses Einstein's photoelectric effect that introduces photons and their energy based on frequency, while also examining the behavior of electrons as waves until observed. The narrative culminates in a discussion of the implications for quantum mechanics, including the observer effect and Heisenberg's uncertainty principle.
