When light passes into another material like glass or water, refraction causes it to bend. However, all the colors of light do not bend the same amount. At one end of the spectrum, red light bends the least, while at the other end, blue and violet light bend the most.
Twenty-four of Saturn's moons are regular satellites; they have prograde orbits not greatly inclined to Saturn's equatorial plane.
About half of Saturn's satellites rotate in the same period as they revolve around the planet. This is caused by the strong tidal forces exerted by the planet on the satellite. The outer satellites are less affected by tidal forces.
