This study presents the comparison between circular and Schrödinger waves. The Hankel functionsH_0^((1) ) (mr) and H_0^((2) ) (mr) which are the solution of circular waves (sink)when combined with e^(-ikt)and diverging wave (source) when combined with e^ikt respectively. Moreover the functions J_0 (mr) and Y_0 (mr) of x=mr suggest that each have a damped oscillatory behavior as x→∞ and that the positive and zeros of J_0 and Y_0 separate each other. On the other hand the Schrödinger wave equation represent that the positive (+) sign is a wave traveling in the +x direction and the negative (-) sign for traveling in the -x direction. In this study the authors have tried to find out the comparison between the circular wave and Schrödinger wave on the basis of monochromatic plane wave.
