Kinematika Gerak Perpindahan Gelombang Air Dipermukaan Bidang Berbentuk Lingkaran

Abstract

Kinematics of motion displacement of water waves in circle surface consider about two-dimensional wave equation in a Cartesian coordinate system by using variable separation method. In entire discussion, the two-dimensional wave equation is transformed into polar coordinate system. By determine the conditions that limit the field of fixed limit where r = R, t value greater than zero and the Bessel functions values are used. Thus, the motion displacement equation obtained, namely Fourier - Bessel equation. From equation, the motion displacement values of wave are found time-dependent.
