1) The Solar and Sidereal days difer from each other by about 4 minutes. How much distance, relative to the Sun and in km, does the Earth travel during that time? (You may approximate the Earth's orbit as a perfect circle.) 2) How many degrees does the Moon move in its orbit during one Earth-day. Use the Moon's orbital period relative to distant stars, i.e. use its sidereal period. 3) a) Since the Earth makes one full revolution every 24...

se 4: Phases of the Moon Everyone has seen the Moon, which is a natural satellite that orbits the Earth. As the Moon rotates around the Earth it is exposed to various amounts of light from the Sun. The reason for this is simple, the Moon at night because it is reflecting light produced by the Sun and because the Earth is slightly out of the direct line of sight between the Moon and Sun. If it were not, a...

Answer the following question on topic shadows and waves A. We are working on the wave model of light. The idea that waves can move around on the surface of a swimming pool or a pond is obvious, partly because you can see the surface of water and the waves have large enough wavelength so you can easily see it. We can see light, but the wavelength is very very short, much shorter than our unaided eyes can see. For...
