Saturn’s ring system shows variation in opacity and spectral properties. Although water ice comprises the bulk of the Saturn’s ring system, non-icy materials also play crucial role to understand the origin of the rings. Particles inside a planetary ring are subject to forcing due to the central planet, moons in the inclined orbits, self-gravity of the ring and other forces resulting from the radiation drag, collisional effects and the Lorentz force arising from the magnetic field of the planet. Study of the ring system got boost after gathering data from the Voyager flyby, the Cassini mission etc. Our study mainly composed of understanding of the C ring and the A ring. It was found that considerable amount of shear gets developed in the vertical direction even within the ring itself and the dissipation it causes can damp excitations due to moons within a couple of hundreds of kilometres. The study stressed mainly on the damping property of vertical bending waves.
