Quantum wavefunction — UPSC CSE 2023 Physics PYQ

Buy PYQ Solution Manual →

A particle constrained to move along x-axis in the domain 0 \le x \le L has a wave function \psi(x) = \sin \left( \frac{n \pi x}{L} \right), where n is an integer. Normalize the wave function and evaluate the expectation value of momentum of the particle.
