How a Rainbow is formed
As we know a prism disperses sunlight into a series of seven colors. When rain falls, raindrops behave like a prism and white light entering the raindrop splits up into seven colors on refraction. These are appeared as Rainbow.
Note: Distance learning – periodic. The student prepares according to the materials handed over to him, then attends a course of lectures that are read for, for example, one month. The culmination of the semester for an undergraduate student is an examination. The final grade in full-time education can be composed of both the amount of current grades and the examination score, and consist only of the evaluation obtained in the exam. In the case of correspondence education, the most important thing is how the student will prove himself at the exam, because he prepared for him during the semester mostly alone, doing episodic work and consulting with teachers. Correspondence education usually lasts less than full-time, because it provides for reduced programs, because a large number of part-time students receive a second education in such images. Usually the correspondence form of training is cheaper than full-time. In general, correspondence education is convenient for those who do not have a lot of free time due to work, family circumstances or health problems.
