Chapter 12, Problem 55E

Interpretation Introduction

Interpretation:Function of type $A\cos \left(Lx\right)$ is not appropriate solution for particle in one-dimensional box should be determined.

Concept introduction:Below mentioned are boundary conditions for particles present in one-dimensional box.

1. Particle is always bounded to be present inside box only and it cannot be present outside box.

2. Total probability to find particle in box is always one.

3. Wave function must be continuous.
