![]() ![]() Since different wavelengths of light shift by different angles inside the water, we get the usual prism effect of light being split in to various bands of color. When the light passes through a water droplet, the curvature of the surface combined with the density of the water in comparison with that of the air causes light to refract, as in a prism. Everyone knows that rainbows occur when light passes through small droplets of water and bounces around, but the following article will explain exactly why rainbows appear as they do. Somehow, we can’t see the end of them, and no matter where we go, they always look like they’re in the same place.

While explanation is a text which tells processes relating to forming of natural, social, scientific and cultural phenomena. It is as a result of systematic observation and analysis. In short, report is a text which presents information about something. It will explain how the rainbow could have happened and why it happened. In the other hand, explanation text describes the occurrence of an event and why this phenomenon occurs. In a rainbow, what are the elements contain so as to forming a beautiful rainbow. It will talk about information the circumstances or elements owned. What makes different between report and explanation text is the scope of the written object. Readers by themselves will catch the impressive point of the object through that showing writing style. Both of a report and an explanation text try to show rather than tell the reader about the factual condition of the object. The purposes of the two texts are to give the information of the object. However, if they are analyzed carefully, the slight difference between the two text types will reveal. Both are the result of an observation that has been done, so it is not a fiction or essay. Such a report and an explanation text have the similarities in the result. ![]() Some text types are quite difficult to differ. ![]()
