Postulates of Quantum Mechanics: Orthogonality of Wavefunctions

The video tutorial explains the concept of orthogonality in wave functions, emphasizing their perpendicular nature. It discusses the importance of normalization in determining orthogonality and provides a mathematical approach using integrals. The tutorial connects these concepts to real-life applications, such as orbitals in chemistry, and explains how wave functions can be viewed as vectors, with orthogonality determined by the dot product.
