This quiz covers the definition of Dirac notations in quantum mechanics, as well as the orthonormal condition and the process of normalizing a wavefunction. It is based on Chapter 2 'Mathematical Tools of Quantum Mechanics' by Dr. Wajood Diery, and explores the properties of kets, bras, and bra-kets.
