Quantum Mechanics

In this chapter, we first discuss the photoelectric effect, its characteristics, and Einstein's approach to this phenomenon. This is followed by the Compton effect and the wave-particle duality. The concept of De Broglie wave, wave packet, phase velocity, and group velocity follows this. Then comes the Heisenberg uncertainty principle with application and energy-time uncertainty. Features of a well-defined wave function and its normalization are discussed. Time-dependent and time-independent Schrödinger equation with an application is described. The problem of a particle in a box has been discussed, and the energy eigenvalue and eigen wave function have been determined under suitable boundary conditions.
