The eclipse is the shadow of the moon entering the earth and the darkening of the moon. The earth has a shadow in the direction of the sun, which is divided into two parts: a shadow and a shadow. The film is not exposed to direct light from the sun, and the half shadow receives some direct light from the sun. The moon sometimes enters the earth's shadow while orbiting the earth, and the eclipse occurs. The whole moon enters the picture, and the whole moon eats; only part of the moon enters the picture, and the moon eats. Sometimes the moon enters only half a shadow, which is called the half a shadow moon. The moon can only enter the earth's shadow (about 16 days old). The size of the level of the monthly diet is expressed by the edible. The score equals the value of the meal, and the part of the moon that enters the picture when the diameter is at the point of the meal is the proportion of the diameter of the moon. The probability of a monthly diet (including a film and a semi-shadic monthly diet) is a maximum of five and a minimum of two times per year。
The principles that form the eclipse and the eclipse are based on the straight-line transmission of light。
The eclipse is a particular astronomical phenomenon, and when the moon runs to the shadows of the earth, the region between the moon and the earth will see a piece of the moon missing because the sun is covered by the earth. The sun, the earth, the moon at this time happens or is almost on the same line. The monthly diet can be divided into monthly diets, full monthly diets and semi-mural diets。
The eclipse, also called solar eclipse, is the movement of the moon between the sun and the earth. If the three are in a straight line, the moon will block the light from which the sun is projected, and the shadow behind the moon falls on the earth, where the eclipse occurs。
