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.
1 Block II and IIA, Operational Satellites: They consist of 28 satellites in total that were launched from 1989 on and many are still operating. 2  They weigh about 1 500 Kg and have a planned average life of 7.5 years. 3  Since 1990, an improved version was used, Block IIA (advanced), with capability of mutual communication.
