In this article author has developed computer simulation using Microsoft Excel 2007® to graphically illustrate the wave functions and their momentum representations. Using this simulations wave functions in different states can be plotted. The expectation values of x and x2 can be obtained by using the simulation. Using momentum representation

and are obtained. Using the expectation values of position and momentum the uncertainty principle verified. The momentum representation is seldom used in quantum mechanics courses hence students find it difficult to understand.
